Flick the two mice: Logitech Logitech G400 & G300s

Last summer, the cousin said that his right-clicking G300s did not feel right. I tried it and it was really. It was estimated that he was playing lol and was abolished. He promised to help him repair it. Later, a classmate said that his G400 wanted to change slightly. I just put these two things together. I always wanted to do it. I never did it. It was always because of various things, or I forgot. Really. Sorry. Wait until my classmate said a few days ago that I quickly got hold of the mouse with him.

In fact, before trying to dismantle the G300s, I looked at the bottom, did not see the screw holes, I actually thought that this mouse is a fixed buckle, holding a crowbar to start, fortunately I can not open nor strong Miracle, give up. Just a few days ago when the students mentioned this, I only remembered to go online to search for tutorials and see how the G300s were removed. Sure enough, the screws were hidden under the floor mats ==

In the New Year, the fretting is impossible to buy. The classmates only have two new ones to replace. The two old ones are not faulty, but they are too soft to be replaced, and they are just replaced by the G300s.

When the classmate's G400 was delivered, it was removed. I just took out the circuit board from the two shells. It looks like a two-piece PCB assembly with 8 pin headers for direct soldering. The left and right keys are OMRON's, and there are diagrams to see the model. The jog of the middle button should not be OMRON's. In fact, there is a third PCB on the G400, locked on the top case, I did not take pictures. There are two JH plugs on the PCB below, which is called JH = = One is the PCB that links the top shell, and the other is the USB cable.

After the demolition and demolition, the above picture was taken and it was thought that it was necessary to record the direction of the micro-motion. After the demolition, there was a directional screen printing on the board, which was also assured.

The two new movements that my classmates bought seemed to be cherry. I didn't look at it and looked at the direction. Welder slag, big gods lightly sprayed.

After this change, it looks like this, nothing new.

The cousin's G300s was taken apart and it was found to be dirty. The G300s were basically sealed. How could it be so dirty? I also don’t understand. Similarly, the left and right keys Omron, 4 G keys should not be, did not pay attention. The use of such a square touch switch in the middle button, no wonder it feels a bit hard. The lower two in the middle are the DPI adjustment buttons. The G300s with the G button looks like the circuit is more complicated than the G400, and the board is also double-sided. The LD5 next to the middle down master should be an RGB LED, four pins, three RGB plus a VCC (I see a + sign, this is a total yang?). Forget to take the light part of the shell, it should be this LED light to make the light bar on the left and right of the shell light up.

The G400 removed the micro-motion and found the same model with the G300s removed.

Similarly, you can see the direction of silk screen when you remove it.

Put it back, as if the left side is a bit embarrassing.

The bottom shell is also dirty, brush brush.

Installed back, bright, left and right keys can be triggered, is the feeling of the left key than the right hard? I look aggressive. . . The test PC did not have Logitech G software installed, and did not measure the light and G key.

It seems that for the first time, the technology will not be able to get home. There will be a chance to slowly come later.
