The ScottoFrog is a 20-key wireless single-handed keyboard based on the FrogPad. The board uses Gateron Milky Yellow switches. The keymap is extremely heavy on combos as many keys or symbols will be typed by chording. It supports Bluetooth wireless using a nice!nano in addition to wired connections over USB-C. You can also build it using an Arduino Pro Micro.
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 nice!nano or Arduino Pro Micro
- 1 3.7v 750mah battery (403450)
- 3 2u plate mount stabilizers
- 20 1N4148 diodes
- 7 M2x8mm standoffs
- 14 M2x6mm screws
- 20 MX switches
- 15 1u keycaps
- 3 2u keycaps
- 2 1.5u 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: 3, 4, 5, 6, 7, 8, 9
Then the rows (red) go from top to bottom: 15, 14, 16, 10
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 you can simply download (right click, save as) and flash using QMK Toolbox:
default.hex - Default QMK keymap.
vial.hex - Default QMK keymap with Vial configurator support.
scottofrog.uf2 - Single-handed ZMK keymap for wireless builds.
