This is my submission for Hack Club's Hackpad YSWS! This is my first time designing a PCB, using CAD, and using QMK. I plan to design a version 2 in the near future.
This MacroPad is currently configured as a launch controller for Kerbal Space Program! If it works, you will be able to control movement, stages, SAS, and thrust using this macropad! The idea came from my friend, and I saw this as a perfect opportunity to make a prototype. I hope you like it! :D

Questions
How big is the MacroPad PCB?
It measures 91.5 × 96 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MacroPad use?
20 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 files?
From the Lermonade/Lerpad repository on GitHub, at the commit this page was made from: the board is pcb/MacroPad.kicad_pcb and its schematic pcb/MacroPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MacroPad design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
