The Scotto16 is a 16-key macropad. It uses Akko Lavender Purple switches and an RP2040 Pro Micro controller.
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 for free 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
- 16 1N4148 diodes
- 4 M2x8mm standoffs
- 8 M2x6mm screws
- 16 MX switches
- 16 1u keycaps
Wiring
When looking at the back of the board, the columns (blue) go to the following pins on the controller from right to left: GP6, GP7, GP8, GP9
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
vial.uf2 - Default QMK keymap with Vial configurator support.
