Creators! Feel free to tip me off about your keyboard related projects to bring them to 140K readers.

The Egboard v2 is the latest iteration of this unibody split powered by a Raspberry Pi Pico running Rust – designed and handwired by Anshul (aka ArchUsr/ArchUsr64) from India.

This is the second project in a row that was designed via OpenSCAD.

Specs

  • 38 keys (5x3 plus four thumb keys per half)
  • unibody split
  • MX
  • Pi Pico controller
  • 3D printed case
  • handwired

The custom firmware is written in Rust, and it supports multiple layers, one-shot modifiers and mouse input with acceleration control.

A big part of keeping the code simple was using the USBD-HID crate for handling the usb side of things. Doing so allowed me to focus on the important things like getting the feel of one-shot modifiers just right. I highly recommend the crate if you wanna build any HID devices yourself – Anshul.
