• Eight RGB LEDs around the edge and one under-key LED, with fully programmable 16 million colour backlighting.
  • Piezo speaker
  • Only 34×34mm PCB. Clearances are sized to be suitable for most 4-layer board services.  
  • Mostly single-sided SMD components so can be built in singles, with minimum special equipment.
  • Nothing smaller than 0402, designed to be built by hand with care. 
  • Small enough to build on a mini-hotplate. 
  • SAMD21 microcontroller with flash, so fully Arduino and CircuitPython compatible.
  • One under-key RGB LED and eight ordinal RGB LEDs around the under-board edge.
  • USB-C for power and data.
  • Kailh hotswap sockets and centre hole to use with any Cherry MX compatible switches. 
  • 3D printable enclosure 
  • M2.5 bolt closure for easy access and hacking. 
  • Optional LED and I2C outputs to connect to other devices. 
  • Able to emulate keyboard, mouse, game controller and have serial communication for bi-directional communication.
