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 for free here if you want to build one yourself.
- 1 RP2040 Zero or Raspberry Pi Pico
- 34/40 1N4148 diodes
- 48 M2x6mm standoffs
- 96 M2x4mm screws
- 1 Pin-Socket Headers (If using RP2040 Zero)
- 34/40 Choc switches
- 34/40 1u keycaps
When looking at the back of the board, the columns (blue) go to the following pins on the controller from right to left: GP29, GP28, GP27, GP26, GP15, GP7, GP6, GP5, GP4, GP3
Then the rows (red) go from top to bottom: GP9, GP10, GP11, GP12
If building the 3x6 variant, connect GP14 (before GP29) and GP8 (after GP3) for the extra columns.
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.
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:
After flashing vial.uf2, you should load the vial.vil configuration file within the Vial application to ensure everything functions as expected.
