Shared by Mae Pugin aka mournepousse/harrael, the KaSe is an open-source angled unibody keyboard inspired by the Atreus62.
I’ve been slowly hacking on a custom keyboard project and I finally feel it’s in a state where I can share it and get feedback. It’s called KaSe, and it’s built around an ESP32-S3 with both USB HID and Bluetooth HID, plus a small OLED display and multi-layer keymaps – harrael.

- 64 keys
- MX switches, hotswap
- ESP32-S3 controller
