This is a computer mouse with USB and PS/2 intefaces. There are 3 buttons and a wheel. The PCB is designed to be placed in a cheap plastic case manufactured in china. I have used the plastic case and lenses from the RX-112 mouse as a donor.
The mouse is compatible with Windows and Linux OS.
The device is based on a Silabs 8-bit MCU EFM8UB20F32. This MCU has a Fullspeed USB controller and adjustable internal oscillator.
