Razer Naga vs. Logitech G700

Logitech New G Series Gaming Peripherals

Razer DeathAdder is Razer’s entry-level gaming mouse, and now it has been updated to 3.5g laser version. However good Razer DeathAdder is, it will not be superior to Razer Mamba which looks similar. Today we will introduce how to make Razer DeathAdder handle better than Razer Mamba. If you open Razer DeathAdder, it just means that you will lose Razer warranty. So be clear about it.

Razer DeathAdder

Regarding to handle, it refers to three kinds of feeling: grip, touch and click. We will change DeathAdder’s clicking feeling.

Razer DeathAdder bottom

There are three screws in Razer DeathAdder bottom. To unscrew the screws, a high quality screwdriver is needed, because this kind of galvanized iron screw is easily to slip.

Razer DeathAdder Internal Structure

There are pretty many modules inside Razer DeathAdder. DeathAdder has total two layers of PCB, and the bottom one is to control light and gaming system, while the top one is for inching and scroll wheel.

Razer DeathAdder main chip

Razer DeathAdder uses Avago S3668 chip which is stronger than normal optical mice with Avago A5030. Be careful about the flex cables, especially the wide ones. Because Razer doesn’t take into account that gamers would disassemble DeathAdder in the design, the flex cables is easily to break in the process.

Razer DeathAdder flex cables

Nowadays, high end mouse all adopts Omoron inching including Razer DeathAdder, but only low-end Omoron inching. The side keys of Razer DeathAdder is the TTC inching.

So, here is the point. How to change Razer DeathAdder clicking feeling? To us, the shortcomings of Razer DeathAdder is the long key regulation and big flexibility. What is the method to shorten the key regulation as well as reduce the flexibility? But all we have is the foot pads.

Razer DeathAdder key part

Foot pads

We stick the foot pads in the button and inching connecting surface as showed in the following pictures. Could it be so easily to achieve the goal? No. After closing the cover and screwing the screws, we find that the key can not be pressed down. Why? It’s obvious that foot pads thickness is larger than key regulation. But we don’t have such a skill to cut down half thickness of those foot pads.

Part of Razer DeathAdder

Razer DeathAdder keys in the casing

We also stick foot pads in the top PCB-the screw position of welding key inching to prop up the PCB and enlarge key regulation between inching and key. So the height which the larger key regulation deducts the thickness of foot pad between key and inching is the key distance, which is shorter than the original one.

Use the foot pad to prop up the PCB and increase the distance between key and inching.

Razer DeathAdder
On the trial, we also add the foot pad in the rear screw position in the PCB which works the same as the abovementioned ones, which provids better and stable effect. It is worth mentioning that the key regulation will be affected by each screw at the same time when you close the cover. It may be resulted from the top and bottom PCB have been near each other after increasing the PCB heights. So don’t try to screw the screws too closely.

Razer Imperator Ergonomic Laser Gaming Mouse Disassembly

Logitech MX518 features 1800 dpi, a sculpted comfort grip and eight programmable buttons, and is one of gamers’ favorite FPS gaming mouse. What’s Logitech MX518  inner structure? Let’s dismantle it.

It is not hard to open Logitech MX518,  which only needs to remove 3 screws in the bottom.

After opening Logitech MX518 top cover, we can see its internal structure. There are two layers of PCBs inside corresponding to different function modules. Circuit design also exits in the top cover.

To turn over the top cover, we’ll see its internal structure clearer.

There are totally two large parts of function modules in Logitech MX518. Let’s begin from the top cover which is simpler.

Logitech MX518 top cover, which has all the buttons, is mainly to realize touch function. Only one circuit connection in Logitech MX518 is to complete side buttons function. In fact, this part of PCB is fixed by the top cover.

A nattier blue lever fixed by a screw can be seen clearly in the above picture. Its part near the white screw is the contactors of side keys, by which it can complete all side keys functionality.

There are also a big and a small inconspicuous contactor near the silver screw seperately, which are to inch the function buttons of Logitech MX518 top cover to perform special functional action. Take the following two pictures for reference, you can easily understand the contactors usage.

The following picture is the PCB in Logitech MX518 top cover, which is also the button position of two side keys and two top cover functional contactors. The entire PCB is connected to the bottom part by a cable.

The total inching switches are Omron products with good durability and handle.

It is worth mentioning that the side keys handle is lighter and softer than the left and right keys because of different resilience settings in their inching switches.

Logitech key module function is fairly concentrated with simple function distinction. After removing the top cover, Main PCB, data cable interface, key control module and inching part can be seen in the bottom plate.

This is Logitech internal inching switch integration, which also uses Omron inching switch. As mentioned above, Logitech MX518 left and right keys resilience setting is harder than side keys, which is also Logitech product consistent feature. And the clicking sound of the left and right keys are louder than two side keys obliviously.

The yellow button is corresponding to the function button before the scroll wheel to realize DPI increasing; the blue part is corresponding to EL grating effect function judgement module to determine scroll wheel rolling and send action signal.

The following picture is the close up view of inching switch integration part. The sliver steel wire is the cause of the scroll wheel clear clicking sound.

Other side view of scroll wheel and inching integration. The signaling cable is connected in the rear part. All the PCBs are fixed by clips and a screw. Flexible steel wheel supports the pressing and upspring of the scroll wheel.

USB and PS/2 the signal transformation function control chip is produced by Cypress semiconductor company and packaged by 24pin DIP; This integrated PCB belongs to low speed USB microcontroller with built-in crystal oscillator, 12MHz operating rate , 8Kx8 programmable memory and 256×8 RAM to save the mouse original and user customize function modules.

Agilent A3080 optical sensor core part is the kernel of Logitech MX518, whcih is mainly used for optimized game and office application.

Microsoft SideWinder X3, a medium and low end gaming mouse, features symmetric design. Let’s disassemble Microsoft SideWinder X3.

Microsoft SideWinder X3 bottom is very simple with only two foot pads to hide screws. The foot pads are 1mm thick wiht 0.5mm black material top and 0.5mm hard colloid bottom, which are really tough and firmly spliced. After removing foot pads, three  Phillip’s head screws come out.

Three screw holes after removing foot pads

Microsoft SideWinder X3 1mm thick foot pads

After we remove three screws, Microsoft SideWinder X3 inner part can be seen, which is quite clear with two-layer PCBs. There are no flex cables inside, which reduce fault probabilities of flex cable breaking down. No PCB is in the top cover. Side keys and DPI adjust button are both directly integrated into main PCB.

Simple inner design reduces fault probilitites

Microsoft SideWinder X3 doesn’t have three layers as usual Microsoft mice do,  but two-layer PCBs fixed by screws and snaps in the top cover like normal all-in-one button mice.
Microsoft SideWinder X3 has the same top inching triggering area and side triggering as IE 3.30, I01.1. To resolve side key looseness problem, SideWinder X3 features hinge connection in the joint part of side keys and top cover. A spring is also used to force side keys to return and hold their position, and avoid the looseness situation for a long time use, which may be resulted from plastic deformation as regular mice side key return rely on material tenacity and inching resilience force.

The DPI adjust button, like a claw, is controlled by inching.

The top and middle cover can be separated after the fixed screw and two snaps in the front key part is off. There are totally three DPI buttons, two springs, two side keys, a top cover, a middle cover and a screw.

All the parts of SideWinder X3 top cover

After dismantling the top part, let’s look at SideWinder X3 core structure. There are double PCBs, and the top one, which fixes DPI adjust inching, is fixed by three screws in the base plate support. A small black rubber covers DPI inching, which is used to control DPI indicator diffusion. The scroll wheel is grating structure as IE 3.0, but with great improvement in module accuracy, tactile response and compact structure.

SideWinder X3 middle button uses a square inching, and a spring on its top to strengthen resilience force. The left-right button and side keys inching, are not Omron white inching which is appreciated by gamers, but Panasonic brownish black square inching, which differs a lot from IE 3.0, I01.1. The PCB near inching  is too narrow for gamers to change OMRON rectangular inching.

SideWinder X3 laser sensor

After removing SideWinder X3 top PCB, main PCB, inching and laser sensor are left. A small black rubber covers laser sensor. A6010 laser sensor in SideWinder X3, which has losing frame and bad compatibility problem in Logitech G5 or Razer Copperhead, performs well and has good compatibility with normal cloth and synthetic resin mouse pads, which may be caused by   AVAGO improvment.

Microsoft adds a little circle cable clip in the joint part of mouse cable and casing to avoid effects on inner circuit components when the cable is pulled. Surprisingly, when we pull the cable clip out, the PCB also separated from base plate. SideWinder X3 PCB is fixed by the scroll wheel pressure and the rubber in laser sensor, and doesn’t resemble the screw fixing methord in other high or medium end mice. Microsoft makes trickery here. It’s well known to all that laser sensor system has high demand on laser sensor, Len and light source relative position. This design may not have influence  on regular operation temporarily, but after a long time, if the scroll wheel is worn or laser sensor rubber is transformed, and then their relative position  changes, SideWinder X3 can’t avoid going wrong.

The back of main PCB (red part is the memory chip)

Microsoft SideWinder X3 Len also adopts integrated design with light source as regular mice. Due to its structure, we can’t take off the Len and light source unless removing sensing chip first. As SideWinder X3 MCU is blocked by the Len on the back of main PCB, MCU specific mode can not be seen clearly.

SideWinder inner part doesn’t feature luxury workmanship as Microsoft hardware always does. It can not be said rough, but also has nothing to do with delicate.

Intergraded light source and Len

Though inheriting I01.1 classical appearance, Microsoft SideWinder X3 performs less powerful on workmanship and function compared than the same kind of  mice in fierce gaming mouse competition.

Microsoft launched the first bluetrack wired mouse- Comfort Mouse 4500. Whether Comfort Mouse 4500 can exceed Microsoft IntelliMouse Optical, Let’s dismantle it to see its inner structure.

First, we remove the mouse foot pads, and then the bottom three screws appear, and they are not Philip’s head screws but six-star screw in short distance.

The three bottom screws as above, the tail  one is bigger while the other front ones are similar.

Due to no PCB flex cables in the top cover, Comfort Mouse 4500 can be easily separated after removing the bottom screw. To avoid the looseness of side keys, two torsional springs are specially added in the side which is different from IE3.0. As the increase of springs, the connection of side keys and top cover is designed as spindle hinge, which is also different from IE 3.0 return design via side keys components’ plastic resilience.

Separated top cover of Microsoft Comfort Mouse 4500

Side keys feature of Microsoft Comfort Mouse 4500

Due to Precise module and new clips structure, it definitely costs us much time to totally dismantle the top cover of Comfort Mouse 4500. It inherits all-in-one three-layer top cover design which is the same as Microsoft Laser Gaming Mouse 6000.

All the components of the top cover, from left to right: top casing, middle casing, main part, two small torsional springs.

The side skid-proof 1mm thick rubber  provides good handle.

Now let’s look into the core components of Microsoft Comfort Mouse 4500- the so called bluetrack optical engine and PCB. Comfort Mouse 4500 has two PCB boards, the front is for the inching and scroll wheel, the rear is key components like bluetrack engine and MCU.

Microsoft Comfort Mouse 4500 PCB

Microsoft Comfort Mouse 4500 base plate is fixed by three Phillip’s head screws. In the LED part, two six-star screws fasten bottom optical lens. MCU is the Sunplus 8 Bit IC.

Due to the specialty of bluetrack, master PCB is risen.

Master PCB identification of Microsoft Mouse 4500

Microsoft Comfort Mouse 4500 adopts Microsoft consistent raster design, which differs from common encoder structure in  other mouses.

For its left-right scroll wheel design, Microsoft Comfort Mouse 4500 is a bit more complex than IE 3.0 structure. The tail scroll wheel has a shifting block to trigger inching of left-right scroll wheel.  A small spring is used to strengthen middle button trigger stress to reduce the misoperation. Though the scroll wheel is fastened by mounting board, it cost much time in dismantle it. After removing scroll wheel and all the screws, PCB can be taken off.

PCB without the scroll wheel

Panasonic brown spot inching is used for left-right keys. It also can be observed that scroll wheel uses raster structure.
Comfort Mouse 4500 also changes the side key structure from overhead inching contact to side contact with better handle, which can reduce a PCB and few cables to decrease fault probability.

All the wielding spots in Microsoft Comfort Mouse 4500 are full and balanced with sturdy workmanship. It surprised us that mouse cables are fixed by wire buckle, screws and binder plate, which is more sophisticated than clip fixings in normal mouses.

The reverse side of Microsoft Comfort Mouse 4500 PCB
Turning PCB overcome, the true feature of bluetrack can be seen clearly.

Comfort mouse 4500 PCB is connected in the plug-in type. Two very delicate pasters are the trigger inching of scroll wheel, providing fairly good handle.

Bluetrack optical engine of Microsoft Comfort Mouse 4500

Bluetrack optical engine special lens is located high. The black part plays the role of fixing highlight light source and proofing diffusion.

Although the top cover is not fixed by screws, reasonable clip structure and close integration of each component in Microsoft Comfort Mouse 4500 can totally guarantee consistent stable handle for a long time.  From the classical IE 3.0 mouse till now, we can see that Microsoft keeps in making improvement. Microsoft Comfort Mouse 4500，with outstanding performance, comfortable handle and simple designed,  gives you the reason to try or own it.

Razer launched the first gaming mouse for the left handed gamers-Abyssus mirror edition, which is really shiny and pretty. Let’s get closer to Razer Abyssus Mirror Edition.

Razer Abyssus Mirror Edition Mirror Edition packing

Razer Abyssus Mirror Edition mirror edition uses the idiomatic black packing and Medusa Logo is in the top right side.

Inside Razer Abyssus Mirror Edition packing

Razer Abyssus Mirror Edition

Razer Abyssus Mirror Edition has ultra long and wide integration buttons, hard side line, thin base plate, and smiling foot pads and so on.
Bright mirror surface features the sense of glaze, which show its low-key and black luxury that totally let the piano lacquer design shame. When it connects to the PC, the back Medusa LOGO emits faint blue light, setting off Razer Abyssus Mirror Edition showy temperament.

The base plate of Razer Abyssus Mirror Edition

It’s a pity that Razer Abyssus Mirror Edition also has black rubber scroll wheel, not as the shiny one in Razer Imperator gaming mouse.

Razer Abyssus Mirror Edition relevant accessory

The accessory for Razer Abyssus Mirror Edition also includes quickest guide, senior user guide, product card, product manual, certificate of authenticity, tags but without light disk as the same. Users, who want to use the senior function, have to download drive in Razer official website. Maybe as Razer drive update is too frequency, Razer didn’t attach the light disk since last year.

Mouse drives certainly also inherit the drive program of Razer Abyssus. Though DPI and response rate can be adjusted by the mechanical slide switchs, several detailed adjustment need to be realized via drive. As an entry-level gaming mouse, Razer Abyssus mirror edition strengthens driver-free design, whose driving is easier than brethren Razer Death Adder.

Let’s begin to disassemble Razer Abyssus mirror edition.

After carefully uncover the rear foot pads, only one fixed screw is in the button. Unscrew this screw, and then the top cover and base plate can be separated. But be careful when open it, because a line supplying electricity for bottom LOGO connects the top and rear case. After removing it gently, the top and bottom case are totally isolated.

Inside Razer Abyssus mirror edition

Razer Abyssus mirror edition adopts integration standard two-layer structure. The buttons are fixed by four clips and three fixed legs. Due to ultra-long button plate, these seven fixing devices are all located at the back part. It can be observed from clips and button legs that button plate is made from translucent white ABS, which is also the reason for the LOGO blue light can pass through the case.

The top cover of Razer Abyssus mirror edition

The middle cover and rear part of top cover get quite close as its fine module workmanship and seven fixing spots. However, the front side of top cover is a bit loose, because the long button plate is only fixed by the front button legs. After disassembled, the translucent pretty Medusa LOGO appears.

Medusa LOGO in Reverse side

Turn over the middle cover of Razer Abyssus mirror edition, the main component of shine LOGO can be seen: A milky highlight LED is fixed in the black spotlight bowl by PCB. There is nothing but the LED, which is quite simple in the PCB. Additionally, PCB is quite small, users have to add another PCB if you want to add a breathe light.

The rear cover of Razer Abyssus mirror edition

The PCB of Razer Abyssus mirror edition

The inner part of Razer Abyssus mirror edition is quite simple, and the mouse cables connect to PCB by plug-in. The joint of cables and cover has a cable case to ensure inner pull durability.
Master PCB is fixed by the top cover instead of screws for cost saving. So it’s easy to pick it out. But pay attention not to lose two slide switches in the PCB back.

Razer Abyssus choose Omron D2FC-F-7N inching in left and right buttons, which is also the main reason for the clear clicking feeling. As same as Razer Adder, Razer Abyssus mirror edition adopts mechanical encoder structural design in scroll wheel. Maybe caused by the short wheel diameter, its rolling damping is a bit hard, but the tactile response is very obvious.

Inching feature of Razer Abyssus mirror edition
To differ from high-end products, Razer Abyssus mirror edition doesn’t have shiny scroll wheel, but the middle rubber and two sides plastic material in scroll wheel of Razer Abyssus mirror edition resembles Razer Imperator. The part near middle inching is thick to ensure scroll wheel rolling and inching.
Different from left and right buttons, central button of scroll wheel adopts TTC inching with slightly hard handle, which keeps the same as button clicking sense. Razer Abyssus mirror edition features Avago optical sensor “S3888” with DPI as high as 3500. It is not an exaggeration to say that Avago optical chip beginning with S is the word for senior optical mouse. Behind the optical board, a transparent lens shade fixes infrared LED, which is the work light source of Razer Abyssus mirror edition. Because infrared is invisibility for human beings, the bottom of Razer Abyssus mirror edition doesn’t shine after connecting to the computer.

Optical sensor of Razer Abyssus mirror edition

The central button uses TTC white spot inching

Turning the master PCB over, most components of Razer Abyssus mirror edition are located in the rear. Many components are pester design to save space. There is IC chip but it’s hard to see its information clearly. Two silver bulks are the sliding components for DPI and response rate adjustment.

Two small metal plates beside optical sensor are just slide switches of Razer Abyssus mirror edition. The rear cover is also made from ABS material. There is a special mouse lens in the rear cover.

Logitech scroll wheel adopts completed mechanical structure, and achieves mode change by the button above. Its metal structure also provides fine durability.
Logitech scroll wheel is well-known for a long time for its excellent workmanship and details. Just a excellent scroll wheel is not enough, however, as a gaming mouse, inching is the question that users concern most.

PCB board of Logitech gaming mouse G500

Let’s look at the PCB board inching, which used the well-received Omoron technology providing good sense of rhythm while clicking. Two metal paster inching are beside the left, mainly corresponding to DPI adjustment key of Logitech gaming mouse G500.

Logitech gaming mouse G500 uses Omoron inching

Some Parts of Logitech gaming mouse G500 use paster inching.

Maybe some people think paster inching is not good. But the fact is opposite. Paster inching with normal handle has been used long before, but a paster inching made of all- metal, with high quality and long life time, is supior than current general inching switch in a certain degree.

The picture above is the internal structure of Logitech gaming mouse which realizes three keys functionality. We have try anything but failed to take it out. To make sure the completion of reviewed product, we have to give up finally. But guessed from the comprehensive factors of space and handle, it may also use paster inching.

Agilent S9500 B0902 chip of Logitech Gaming Mouse G500

The secret for good compatibility in Logetic gaming mouse G500 is this Agilent chip numbered as S9500 B0902 with huge size, which is more massive than other brand mouse. As Logitech doesn’t use separated slot design, we can not get the double layer PCB board out. After observation, this component is directly  welded.

So the disassembly is over till here. But we are satisfied that we have knew the fact of inching, PCB board, core positioning engine in Logitech gaming mouse G500.

Summary:
Logitech gaming mouse G500 features 5700DPI laser positioning engine, showing high quality and good practicality. In the disassembly, the excellence internal structure not only inherits Logitech workmanship, but also is careful at each accessory.

Logitech G5 Laser Mouse Disassembly

Today we dismantle Logitech G5 Laser Mouse. Logitech G5 excellent performance including powerful and dazzling appearance, also from its internal sophisticated and ingenious mechanical design.

Logitech combined so many accessories into one, its sophistication is worth being praised.

Logitech G5 makes you feel simple and stylish.

Logitech G5 uses six screws for fixing the lower location, it is difficult to see in other mouse.

Logitech G5 DPI adjustment button.

Logitech G5 can adjust DPI value, and indicator in the mouse can display the current status. Logitech G5 can deliver up the working location through the corresponding location LED lighting to show the state of mouse DPI purpose.

Logitech G5 reserve out of the indicator in the upper cover.

Logitech G5 buttons fixed on the side of top cover, which is equipped with soft and full of plastic material toughness, can provide a soft stretch when clicked.

Overall, Logitech G5 with a four-way scroll wheel technology, a large number of shortcut keys, and laser diode, but the circuit board is designed to be relatively small part, high integration. This is mainly because the rear right place to reserve a place with weights.

From the above we can see that Logitech G5 circuit board is divided into two, in front of this piece of circuit board on four-way scroll wheel and 8 buttons of the micro switch.

Button in the main use of the micro switch, Logitech G5 upholds the tradition of the past left and right buttons, is equipped with micro-switch OMRON. Logitech G5 only side button using the ZIP micro switch.

Logitech G5 applied the four-way scroll wheel technology, the technology only used in MX1000 among the MX series of previous generation products. We can see that four-way scroll wheel also sets out a bracket, bracket front end fixed on the circuit board, stand between the subject and fixed office to connect through a shaft, so although bracket is fixed, still can influence the toggle wheel. In support of the back-end has a spring , can provide wheel left and right, press the appropriate DIP or stretch.

Logitech G5 equips with a spring, a hole diameter larger than the ball would be caught in between the bearing and the wheel, so that when the toggle wheel, fixed on the wheel bracket and ball bearings to keep fixed, while the inside wheel design detailed bump lines, thus being naturally produced paragraphs feels.

Optical engine is definitely the soul of a mouse, directly determines the performance of this mouse. Logitech G5 using the Agilent S6006 optical engine, which is specifically designed and  developed for the laser optical mouse. Maximum support 2000DPI resolution, 6.4 megapixels to provide / sec image processing capability.

Here is fixed on the engine side of the laser diode optics, and Logitech G5 laser light level is low, will not harm the human body. The introduction of laser diode can bring a wider range of interface adaptation and game performance.

Logitech G5 optical lens components, laser hair injection of light through the components to the desktop, laser specular reflection occurs on the desktop after the vertical upward part of the lens components will be absorbed and transmitted to the optical engine CMOS matrix, then optical engine optical signal will be collected for processing, and information operations by moving the mouse.

Logitech G5 can  display the current DPI setting the mouse state, because there may be some light at the circuit’s LED lights, 4 LED light-emitting diodes were placed in a separate small circuit board, a small circuit board and through the flexible cable connection on the main circuit board.

People who familiar with the mouse internal structure should know the mouse has two chips, one is optical engine, the other is control chip. Control chip for the coordination of various signals within the mouse clock, synchronized through the USB port after re-sent to the computer. In addition, the Logitech G5′s programmable shortcut keys also need to control the chip support. Logitech G5 as welding together of two circuit boards, so one control chip (designated red circle position) of the specific information we can not see inconvenience.

Logitech G5 with adjustable weights to suit different user needs for the weight of the mouse.

Weight block size is moderate, the bottom has a button with brackets, after installation is completed, press the mouse button on the bottom rack of the button will trigger a counter weight bracket on the body, so that will be assigned weights successfully removed.

Summary:  We know Logitech G5 through dismantling. Its interior design, intricate parts and a high degree of integration that we re-acquainted with Logitech G5 Laser Mouse Disassembly.
