The VColChoc44 is an Atreus-like low-profile monoblock split by jpconstantineau with on-board RP2040.

My thinnest, most portable keyboard! – jpconstantineau.

This open-source keyboard, inspired by the Atreus and based on the PyKey60, features an on-board RP2040 and CircuitPython for easy keymap update.


  • 44 keys, low-profile Kailh Choc with hotswap sockets
  • on-board RP2040 controller with CircuitPython
  • 14 mm height from desk to top of keycaps
  • speaker/buzzer on board

Why did I create a custom board instead of using a Raspberry Pi Pico? The Pico wouldn't allow for the thinnest keyboard. Its position would need room below the PCB and thus would also need a bottom plate to enclose it all, defeating the whole point of an ultra-low profile keyboard.

Another monoblock split with column splay and all the bells and whistles. Designed by 1m38.



This handwired monster is tentatively named the Phatty105 (keymap) and is based on a (surprise!) CRKBD. Committed by jamopopper.
