README
README.mdNextGen Macropad
The Next-Gen MacroPad is a fully DIY, multi-purpose macro pad kit. It's got programmable keys, it looks cool, and most importantly — I made it. A 14-year-old made it. So if it breaks, don't be too surprised, but also it probably won't break because I tested it a bunch.

Questions
How big is the Next Gen MacroPad PCB?
It measures 80.4 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Next Gen MacroPad use?
85 parts, built around the ESP32-S3-WROOM-1-N8, AP2112K-3.3, TP4056-42-ESOP8 and SK6812. 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 Next Gen MacroPad KiCad files?
From the DevX-Dragon/Next-Gen-MacroPad repository on GitHub, at the commit this page was made from: the board is KiCad Files/NextGen Macropad/NextGen Macropad.kicad_pcb and its schematic KiCad Files/NextGen Macropad/NextGen Macropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Next Gen MacroPad design in my own project?
Its repository states no licence, so its author keeps all rights: ask DevX-Dragon before reusing the design.
