README.mdMacAndCheese-ropad
The MacAndCheese-ropad is a 4x4 macropad running on a Xiao RP2040. All 16 of the macropad buttons are fully customizable with the QMK firmware or other firmware that the RP2040 supports.
The MacAndCheese-ropad is intended to be used for daily tasks like copying, pasting, taking a screenshot, ect. THe buttons can also be used as extra function buttons (up to 8 on MacOS and 12 on Windows). Using more adanced software, the buttons could be tied to app specific functions or really anything that can be run on a computer.
Learn more about button use for QMK here: https://docs.qmk.fm/keycodes_basic
I built the MacAndCheese-ropad because I thought it would be a fun but not to hard challage, it has been just as expected. While some of it was smooth sailing a lot was feeling like I was in the dark on many things, however I was able to pull through and continue the project. I hope this macropad makes me more productive and proud to have somthing I worked hard on be usful to me.
The Design:
The design features 16 square keys layed out in a 4x4 grid.
- The keys are Cherry MX switches.
- There is a empty space right of the keys which holds the Xiao RP2040.
The PCB:
The PCB uses a matrix to support all 16 keys, a photo of the PCB in KiCad is below:
The Firmware
The MacAndCheese-ropad uses the QMK firmware to give the keys uses, currentally the firmware is set up with 2 layers of keys. (The exact set up is in the repo).

Questions
How big is the MacNCheeseV2 PCB?
It measures 103 × 84 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MacNCheeseV2 use?
33 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 MacNCheeseV2 KiCad files?
From the asuperidea/MacAndCheese-ropad repository on GitHub, at the commit this page was made from: the board is PCBs/MacNCheeseV2.kicad_pcb and its schematic PCBs/MacNCheeseV2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MacNCheeseV2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask asuperidea before reusing the design.
