The hardware is based on an arduino leonardo, but heavily modified for this application.

Some key features are:

  • Laser Gaming Sensor (up to 8200 cpi and 12,000 fps)
  • Arduino compatible (but requires special board file and modified bootloader)
  • usb and bluetooth connection
  • charge Controller for optional LiPo battery
  • 5 buttons by default
  • i2c extension port
  • all parts are printed with a normal FDM printer
  • hardware and software are made using open source software (KiCad, OpenSCAD, ArduinoIDE)
