A litte UI package (hardware / software) for building simple list like UIs for µcontroller projects.
The hardware is split up into 3 main parts.

- 5 keys arranged as a cursor cross with unmarked caps and a legacy hollow shaft encoder
- Interface split & Signal conditioning
The three components / boards are interconnected by standard ribbon cable with microMaTch connectors
The TFT board is a small connector board only holding the ribbon cable connector and the transistor for the backlight control.
