From the project
Framework for building ergo keyboards
This project aims to provide components for building modular ergo keyboards by separating one main PCB into central and side parts. Side is a dumb PCB, with key matrix only (up to 25 keys), and accepts all switch types (MX/ChocV1/ChocV2/GLP). Central is a keyboard brain, which contains any MCU (wired/wireless/integrated) and additional hardware - encoders/touchpads/trackballs/displays/etc, while keeping its size under 100x100mm. PCBs are interconnected with 12-pin FFC cables, and can be replaced/updated independently.
