Getting One
If you’re interested in getting one assembled, contact me and we can discuss the components and other details for a commissioned build. However, the files are available here if you want to build one yourself.
In addition to the 3D printed case, heat shink tubing, wire, and copper, you'll also need tools along with the following components:
- 1 RP2040 Pro Micro
- 37 1N4148 diodes
- 1 3u plate mount stabilizer
- 6 M2x5mm screws
- 6 M2 heat set inserts
- 12 4x90mm Poron gaskets
- 37 MX switches
- 26 1u keycaps
- 8 1.25u keycaps
- 2 1.5u keycaps
- 1 3u keycap
Wiring

When looking at the back of the board, the columns (blue) go to the following pins on the controller from right to left: GP2, GP3, GP4, GP5, GP6, GP7, GP8, GP9, GP29, GP28
Then the rows (red) go from top to bottom: GP22, GP20, GP23, GP21
Keep in mind, you can connect anywhere on the column or row to the controller, it doesn't need to just be at the end.
Firmware
You can find the firmware files on the qmk_firmware repository or you can compile them online using the QMK Configurator. However, QMK is often slow at getting changes merged and because of that you can find the most up-to-date firmware on the ScottoKeebs Github repository. Also available are the pre-compiled firmware files that are ready to flash:
default.uf2 - Default QMK keymap in QWERTY.
vial.uf2 - Default QMK keymap in QWERTY with Vial configurator support.
scotto.uf2 - My personal QMK keymap in Colemak.
After flashing vial.uf2, you should load the vial.vil configuration file within the Vial application to ensure everything functions as expected.
