This is a QMK-compatible replacement controller for the HHKB Lite 2, identified by model numbers PD-KB200W/U or PD-KB200B/U.This Lite version of the HHKB is a membrane keyboard and not exactly popular compared to more expensive Professional versions that use Topre switches. But the wiring is simple and is a good first project for modding commercial keyboards.This replacement uses a Teensy 2.0, which is cheap, has plenty of pins, and works well with the QMK firmware. The entire controller board is replaced, so you will lose the built-in USB hub. You will gain all the benefits of the powerful QMK and similar Teensy-supported firmware.
