README
README.mdUSB-Keyboard-Adapter
An ATmega32u4 based keyboard controller. This was designed for use with a Psion Series 5mx keyboard, but should work for other keyboards also.
- PCB contains KiCad files for the device itself
- Firmware/Psion-Keyboard-Firmware contains an Arduino sketch for the firmware
- Firmware/ScanTheMatrix is a sketch for scanning the matrix of a keyboard. This is only meant as a tool to map a keyboard with an unknown pinout.

Questions
How big is the TestRig PCB PCB?
It measures 164 × 73 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TestRig PCB use?
95 parts, built around the TS5A3357DCU and TCA6424ARGJ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TestRig PCB KiCad files?
From the RasmusB/USB-Keyboard-Adapter repository on GitHub, at the commit this page was made from: the board is TestRig/v2/TestRig-PCB/TestRig-PCB.kicad_pcb and its schematic PCB/Keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TestRig PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask RasmusB before reusing the design.
