Scotto108 Handwired Keyboard

Scotto108 Handwired Keyboard

The Scotto108 is a 108-key full-sized ortholinear keyboard with a 7u spacebar and 4 macro keys above the numpad. It was designed and built as a Christmas gift for my parents. I used Outemu silvers in my dads and reds for my moms. Everything is powered off a 16mb RP2040 board which is one of my favorite microcontrollers.

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:

There are a lot of screws in this build so I recommend buying extra just in case I counted wrong or you lose some while building it.

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, GP10, GP11, GP12, GP13, GP14, GP15, GP29, GP28, GP27, GP26, GP22, GP21, GP20, GP19, GP18, GP17, GP16

Then the rows (red) go from top to bottom: GP0, GP1, GP2, GP3, GP4, GP5

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:

default.uf2 - Default QMK keymap in QWERTY.
vial.uf2 - Default QMK keymap in QWERTY with Vial configurator support.
