So basically, this is a 3x3 macropad, except it has a unique function: you can enter specific chains of digits to do "secret" functions (preset or customisable), just like entering a cheat code in a game.
main components used
- A SW10 Rotary encoder switch
- An RP2040 Xiao Seed Studio microcontroller
- 0.91" (i think) OLED Display

CAD (Onshape)
the casing is split into three pieces:
- the "cushioned" base that has a lowered part for the xiao to go (since my xiao is inconveniently on the bottom half)
- the walls (with a usb hole to plug into the xiao)
- and the cover
notices:
- THE combopad.ino CODE IS NOT FINISHED YET. I WILL UPDATE IT ONCE THE MACROPAD ARRIVES.

Questions
How big is the MyMacropad PCB?
It measures 63 × 78 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MyMacropad use?
21 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 MyMacropad KiCad files?
From the nathany213/combopad repository on GitHub, at the commit this page was made from: the board is PCB/myMacropad.kicad_pcb and its schematic PCB/myMacropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MyMacropad design in my own project?
Its repository states no licence, so its author keeps all rights: ask nathany213 before reusing the design.
