Overview
Macropad kicad is an open-source printed circuit board by mrdarip, from the mrdarip/macropad repository on GitHub. It is a 2-layer board of 81 × 90.5 mm with 29 parts on 26 nets, routed with 92 tracks and 1 via.
Its parts include 12 diodes, 12 switches, 1 IC and 1 connector. It belongs with the keyboards and input boards of this library.
README
readme.mdbidirectional macropad
This is my submision! it is made to be a macropad, but it can also be used as a numpad, or a gamepad, or a keyboard, or a mouse, or a joystick, or a MIDI controller, or a... you get the idea. It can be rotated to be used in a vertical or horizontal position, so its like a 2-in-1!
to get the case for the rotated version, you just change the x and y values in the .scad file, and you're good to go!
Features
- cool silkcreen art
- a rotary encoder with push button
- An 0.96" OLED screen
- Cool silkcreen art
- 11x keys
- kmk firmware! with layers for different programs!

Hope it looks pretty to you!
[x] I ran DRC and there are 0 errors
CAD
Designed using OpenSCAD! I like it for allowing me to make fast changes (and a slower development process lol).
It's made to be 3D printed, and as it doesn't need supports nor any post processing, mass produce.
Firmware
I wrote the firmware using kmk, you can see it inside the repo. It's pretty simple, but I'm proud of it!
BOM
- 1 SEEEDUINO XIAO RP2040
- 11x switches (I guess any will do), although I like those red ones (I have no idea about keyswitches)
- 12x 1N4148 diodes
- 1x SSD1306
- 1x rotary encoder
IMPORTANT
- Dont send the 3d printed case
I'll print it myself so I'll get less customs fees. - Don't send the OLED screen
I have a bunch of them, less customs fees. - Don't send the soldering iron
I have one, less electronics waste, less customs fees.

Questions
How big is the Macropad kicad PCB?
It measures 81 × 90.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad kicad use?
29 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.
Where can I download the Macropad kicad KiCad files?
From the mrdarip/macropad repository on GitHub, at the commit this page was made from: the board is pcb/macropad_kicad.kicad_pcb and its schematic pcb/macropad_kicad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad kicad design in my own project?
Its repository states no licence, so its author keeps all rights: ask mrdarip before reusing the design.
