Circuit diagrams and firmware source code for Gboard DIY keyboards

for half-life
JoystickMacropad is an open-source printed circuit board by insert-joke-here, from the insert-joke-here/JoystickMacropad repository on GitHub. It is a 2-layer board of 165.5 × 65.9 mm with 16 parts on 36 nets, routed with 78 tracks and 0 vias.
Its parts include 6 diodes, 6 switches and 2 resistors. It belongs with the keyboards and input boards of this library.
This is a 2x3 macropad + a joystick. (created so i can play more pc games and also for the hackclub program half-life!)
It can be plugged straight into your computer (maybe with an adapter if you need it?) and used as a keyboard/joystick however you wish!
It uses an adafruit feather 328p (which is compatible with the arduino IDE , so you can in fact use an arduino with the same code, but you will have to edit the footprint), this was just a cheaper option. The joystick provides analog input to two analog pins on the board and a digital input for whether the joystick is pressed down. The keys use a row / column setup, with a digital GPIO pin used for each row and column, actually saving a (wow 1 whole) pin over wiring each key to a pin. The code to check a key works by setting a row to HIGH, then checking each column to see which pin is active.

It measures 165.5 × 65.9 mm and has 2 copper layers, 1.6 mm thick.
16 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the insert-joke-here/JoystickMacropad repository on GitHub, at the commit this page was made from: the board is JoystickMacropad.kicad_pcb and its schematic JoystickMacropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask insert-joke-here before reusing the design.
