From the project
An Psion to USB keyboard controller
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.

TestRig: common questions
How big is the TestRig PCB?
The TestRig measures 68.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the TestRig?
13 components, from 13 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the TestRig design files?
From the RasmusB/USB-Keyboard-Adapter repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the TestRig design in my own project?
The repository has no license, so all rights stay with RasmusB. Use it as a reference, and ask the author before reusing the design.
