DIY Mouse Upgrade: Switch from MICRO USB to TYPE-C

If your mouse is small and exquisite, it is suitable for people with small hands to use the internet and work, but unfortunately, it has a MICRO USB charging port and the port does not have data transmission function. Compared to the anywhere3, it lacks TAPEC interface and electromagnetic scroll wheel, but it can be converted to TYPE-C charging.

The mouse structure is compact and reasonable. When opened, you can see a PCB board, battery, and side panel, all on the bottom plate.

First, remove the MICRO USB interface, clean it up, and expose the hole.

The original bottom plate has a metal piece that mainly fixes the original interface. The size of the position left by the metal piece matches the MICRO USB female port, but to change to a TYPE-C port, the metal piece must be removed, otherwise it will not fit. At the same time, it is necessary to trim the plastic card slot on the bottom plate appropriately.

Next, trim and shape the 6-pin TYPE-C female port, place it on the PCB board for verification, and pre-tin it based on the soldering points on the PCB.

Next is the soldering process. First, use a hot air gun to combine the reserved tin on the female port with the PCB board (this step can actually be omitted, as the following step is sufficient). Then, perform supplementary soldering on the back of the PCB board for the 4 pins.

The next step is critical. Based on the PCB board's wiring, perform flying wire. Since I do not consider the PD protocol and only need to use the USB charging function, only two wires are needed. Be careful of the positive and negative connections. If connected incorrectly, it may smoke.

The last step is to expand the hole in the outer casing. Be patient and careful.

OK, charging is complete.
