  • 40 keys split ortho
  • MX Kailh hotswap sockets only

  • Bluetooth only (no TRRS jack) MCU (Karl used a nice!nano)
  • you can fit a battery the size of a MCU on the opposite end of the PCB (e.g. a 250mah)
  • open source
  • plate outline available in SVG/DXF formats to order a nice acrylic one (or an FR4 plate by importing it into KiCAD)
