Changes

  • The PCB DXF was extracted from sporkus's case step file. It uses MX and EC11 footprints and is powered by an RP2040 Core-A instead of STM32. Designed via EasyEDA.
  • PMW3360 trackball sensor footprint added.
  • Top case modded with a large circular cut-out for the 25mm trackball holder, friction fit sitting flush with the PCB with the sensor underneath it.
  • Two top case variants: One for the extra MX key and another one for the EC11 in the center.
  • Bottom case modded with MCU cut out so that the 3mm board doesn't rub the bottom case.
