The Scotto2 is a 2 key large button gamepad designed for accessibility. It uses 4 MX switches per big switch in order to make easy to press large accessible buttons. It was custom built for an individual who is a quadriplegic so they could play racing games.
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, and wire, you'll also need tools along with the following components:
- 1 RP2040 Pro Micro
- 8 MX Switches
- 7 M2 Heat set inserts
- 7 M2x8mm countersunk screws
Wiring
This board is super simple to wire. Each half is chained together on 4 of the pins, it doesn't matter which. Then the remaining pins are chained together between all 8 switches to form a ground plane. The left button goes to GP13 and the right goes to GP15 with the 8 chained switches going to GND.
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.
