Show HN: A Truly Modular Keyboard

A modular keyboard system, the Keybit and Keyword, are designed and developed using KiCad and Onshape. The Keybit is a single key with a Cherry MX switch and a CH32V003, featuring pogo pins for connectivity and programming. The Keyword is the main board that connects to the Keybit, consisting of two stacked PCBs with an STM32WB55RGV6, antenna, flash, USB-C, charger, and buck-boost converter. The system is fully programmable and customizable.
