Teensy 2 controller board replacement for HHKB Lite 2
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.
