Order 1.2 thick PCB! Full BOM now included!

This PCB is meant to replace the micro USB port with a USB C port for the MX Ergo trackball mouse.

The latest revision of the Gerber files now includes the ESD traces and thicker traces for power. See last two photos for gerber file pictures. The PCB is still the same functionally. I had to find substitutes for some components, but I was able to verify that the mouse still charges and still functions as it would untouched. That being said, do this project at your own risk.

I had to measure the components on the OEM board to find values and I had to find substitutes for a few components as the original ones are hard to source using common suppliers like Mouser or Digikey. As of now I fully verified that the included BOM works the same as the OEM but they are different. I was not able to identify the value of FB1 or L1&L2. I resorted to using values that made sense. You will also notice that I was not able to source the same connector that is found on the OEM PCB for the flex cable. The one I found works the same but without the latch.

If you are able to provide any information related to components or issues, please don't hesitate :)

This board can be ordered fully assembled but you can also order this board as a transplant PCB. You will however need to order the USB C port, R4, and R5. I do recommend also ordering SW1 and J1 just in case the original ones get deformed during desoldering. These part numbers can be found in the BOM.
