It's so cool! A Mouse with Four Years of Silence--Logitech M325 Dismantling Analysis (Compared to M557)

Time flies, everything around me is changing, but there are still some small objects to accompany silently. These years, from the newly educated society, we are now able to stand alone and the path we have taken is clear. Silently glanced at the mouse in his hand, originally had been with him for almost four years. In commemoration of this glorious mouse, he deliberately demolished him to see what was going on inside.

The mouse was purchased in the second year of my first job. I purchased it in 13 years. At that time, in order to pick a mouse that was easy to use, it was precisely this mouse that made up Amazon's activities, so I started it. For so many years, I hadn't had any problems. The battery is also very durable. Prior to this, the wireless mouse used by Pennefather and Microsoft had already been broken. So many years later, this mouse is still selling, but the price has dropped a lot.

Another contrasting mouse is worth buying Amway, because the laptop comes with Bluetooth, and the USB interface is only three, so I purchased this Bluetooth mouse: (The article contrasts with the Logitech OEM purchased on Taobao Toshiba OEM557 version is really false please distinguish yourself, irresponsible recommendation, in addition to Bluetooth 3.0 is a big flaw, the price of less than 100, this Bluetooth mouse is still very good workmanship.)

In 2015, Logitech made adjustments to the brand in order to upgrade the brand and adapt to the development of the era. The new logo is more flat and more atmospheric. Over the past few years, many Internet bigwigs have made adjustments to Logo, such as Microsoft, such as Apple, this is still a flat era!

Logitech is a Swiss company focused on innovation and quality. It designs a variety of personal peripheral products to help people enjoy a better digital world experience. We started with the mouse in 1981. It (something new at the time) provided a more intuitive way of interacting with a personal computer. We have become a global leader in the field of computer mice, and have reinvented the mouse in a variety of ways to meet the evolving needs of both PC users and laptop users.

Logitech began in 1981, LOGO has changed for four or five, and in fact I probably only seen the back three, the first two should be the LOGO of the computer industry in ancient times!

From the above three mice, you can see vaguely that the size of the M325 is smaller, but the appearance of the M325 can be seen more subtlely. To be dismantled part of the M557 and M325 dismantling comparison, even if the M170, this mouse is nothing to talk about, entry in the entry, stable use on the line.

↑ Comparison of the three mouse parameters, the official website parameters are relatively simple, you can only see this information, and specifically look at the content that will be opened.

↑ The upper part of the mouse has a fluorescent coating that looks very textured, and the finger part has a concave design, and the touch is still very comfortable.

↑ The mouse wheel supports the left and right buttons, and the dense rubber grid on the scroll wheel feels comfortable. The official promotion of this scroll wheel is very suitable for browsing the web. Indeed, just touching this scroll wheel may not be suitable. If you use it for a long time, you do not want to use other mouse. Look at the picture below:

There is a dense rubber grid around the circle of the mouse, and the non-slip provides a delicate touch. This is one reason I didn't want to give it up for so many years.

After using it for many years, the rubber lines in the position of the thumb have been flattened and placed in the backpack. There are more than one place where other hard objects are scratched.

There is a small indicator above the mouse. When it is turned on, it will show green for about 10 seconds. When it is low, it will show red.

印刷 The printed logo on the back of the mouse, as well as information on the battery compartment and information on the switch buttons, have been worn out, leaving a seal. The mouse pad is very kind, using a soft rubber mat, and comfort has also improved.

In order to dismantle the M325, I took the four mats apart and found no screws. . . The model sticker was torn and no screws were found. Finally, after the detailed information sticker in the battery compartment, the only one screw of this mouse was found:

After finding the screw, open it and open it. Dismantling is very simple, if everyone is also using this mouse, it is a very simple thing to want to change the fretting or maintenance and clean up the mouse.

After you remove the cover, you can see the mouse's circuit board and scroll wheel and other components. The structure of the mouse is actually very simple, micro-motion + wheel + button + laser sensor tube, something.

↑ Because the mouse itself is very small, the space left inside is very compact, leaving a large space on the circuit board for the battery, so it is very irregular.

The chip is NRF31512C, Logitech most wireless mice use this chip, part of the NRF24LE1G, the specific parameters can not be found. For users, as long as stability is good.

It is a pity that the mouse's fretting did not use Omron's. Instead, it used HIMAKE's micromotion from Taiwan Huajie, which was not very kind. This micro-motion is also good to use, and it's not much different from Omron's feel. However, it is also a simple matter to make micro-motions. There are also Gods who have written related original works. As long as the three out-points on the back side are opened with electric iron, then new micro-motions can be welded. It is also possible to see that this mouse's PCB board is relatively thick, which is one of the strong backings that have not been a problem for so many years.

In the past four years, the mouse is usually not a very good travel environment. There are a variety of unknown things accumulated in the scroll wheel. . .

Regardless of these, first talk about how the mouse is used to cool it, this scroll wheel is designed specifically for browsing the web, these years with a notebook to go out, always with this wireless mouse, because look at the web or see The document slides very quickly, and now this technique is used in the Logitech Master Series mouse. There is also a spring under the roller, which also helps the operation of the roller on touch.

After cleaning up the inside of the debris, the feel of the installation back to the wheel has greatly improved! Let's go over this GIF again!

Finally, it's good to go back in the order of dismantling! Note that the snaps should not be broken. After all, they are plastic snaps!

M557's appearance analysis station has been done, and the photo shoot is very beautiful, I do not take the appearance of the photos, the appearance is indeed good, because the current notebook comes with Bluetooth, I also recommended a few friends bought this paragraph. Specific Taobao search related information.

The disassembly of this mouse is more troublesome than the M325. To remove the two pads, there are two screws. After a total of four screws are unscrewed, the mouse can be opened with a single click. But be careful, there is a power cord inside, don't break it!

After opening up, it is probably like this.

↑ The work of the entire board looked a bit more refined than the M325.

Look at OMRON again, the model is: D2FC-F-7N, made in China!

Bluetooth module is BCM20730, not Bluetooth 4.0, Bluetooth 3.0. There is a description of this Bluetooth chip on the Internet:

This is a laser sensor. The head is large, and the welding process is still quite good.

The key to the scroll wheel and the device to receive and send are here. There is a point here. If everyone's mouse wheel feels a malfunction, it is very likely that there is dust on the grille. Open it and clean it.

Finally, come to the legendary Toshiba Mouse's mouse on the Logitech standard.

M325 is a qualified wireless mouse, for business people who travel frequently, the appearance is generous, and work is also the style of the big factory, with the undamped wheel, it is still very practical. However, due to cost reasons, the shrinkage of the components is also within the acceptable range.

M557 is well-crafted and has solid materials. However, since Bluetooth is the 3.0 version, it is now Bluetooth 4.2, which has greatly reduced energy consumption. Now it is not appropriate to start M557. Do not mind the Bluetooth version, but only for stability can start.

The above two models are all office wireless mice. The use of home or mobile office is not bad. Do not play games and you will cry.
