A fully custom gaming mouse using a PixArt PMW3389.
2 versions. 3.3V/8MHz Arduino Pro Micro (ATmega32U4) and Seeed Studio XIAO ESP32C3.
I also intend for this mouse to be easily repairable.
- High performance sensor: 16,000 DPI via PixArt PMW3389 - Modular and Repairable - Hotswap Main Switches: Uses Mill-Max 3305 so can be replaced with no soldering - Replaceable MCU: Mounted using through-hole pin headers - Wireless and wired versions. - Sensor communication through SPI
