The MPA is a 42-key split keyboard built around Choc V1 switches using Chocfox (CFX) spacing. Wireless via e.g. nice!nano, designed and shared by miwayho/inpudiy .
I made this project in order to maintain Chosfox spacing (17,5x17,5mm). If you use Chosfox keycaps in projects with choc-spacing, you get gaps – miwayho.
The layout and column-stagger was inspired by the Jian keyboard.
