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.
