A optical mouse replacement pcb for the Amiga pregnant mouse
Removed the solder bridges, and just allow gnd on both sides of the switch.
Requires an XAIO SAMD21 and a ADNS9800 Laser, which you can get still get from Aliexpress. Make sure to also get the Lens.
This is for the version 1.0 of the board. v1.1 don't need to do this apart from making sure your switches are the correct way for 2 or 3 button mouse.
In commodore's wisdom, there are differences in the mouse button pcb layput between the 2 button and 3 button versions. By default i have set the orientation in the 2 button version, as i did not have access to the 3 button pcb layout and they…
