bidirectional 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!

PCB

Here are pictures of my pcb:

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.
