Corne EEC (Corne Extended Electrostatic Capacitive)

Corne based EC keyboard with number row and one additional thumb key.

I'm not electrical engineer. PCB design might not be optimized and buggy. Use this project at your own risk.

Features

• Corne like design, but have number row and 4 thumb keys. Total 28 keys on each halves.
• Onboard STM32G0B1KET MCU, USB-C with ESD protection
• No 0402-sized or smaller SMD(Except optional SOD-323 sized ESD chip, It's stil not diffcult to hand soldering).
• Alomost no through Hole parts.
• Extra PCB can be connected through 1x10 FFC connector(0.5mm pitch. 8 GPIO with 3.3v power line). I will add encoder and LCD display later.

Firmware

The Rust based firmware hosted in separated repo daehyeok/corne-eec-rs.

Credit

This project forked from Cipulot/CorneECRevival.

Design and selecting component based on Cipulot's awesome works. He released multiple EC keyboard PCBs, including popular layouts such as HHKB, EC60, and Corne. If you need a reference for designing your own board, Check his repos.
