Overview
Rhythmpad is an open-source printed circuit board by sneakiee, from the sneakiee/rhythmpad repository on GitHub. It is a 2-layer board of 90.5 × 76.2 mm with 27 parts on 30 nets, routed with 117 tracks and 4 vias.
It is built around the SK6812MINI-E. Its parts include 16 diodes, 10 switches and 1 IC. It belongs with the RP2040 boards of this library.

This was a YSWS project for Hack Club's hackpad for hack club's highway! I got the idea of creating a hackpad for rhythm games, but I also wanted to generalize it more for music, so I decided to make it into a drum-pad by creating square keycaps! The switches are mapped to the numpad from 1-9 and the extra button on the right being 0. This was my first actual hardware project and I hope to build more because it was a frustrating fun (I need to feel more of that.

Questions
How big is the Rhythmpad PCB?
It measures 90.5 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rhythmpad use?
27 parts, built around the SK6812MINI-E. 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 Rhythmpad KiCad files?
From the sneakiee/rhythmpad repository on GitHub, at the commit this page was made from: the board is PCB/rhythmpad.kicad_pcb and its schematic PCB/rhythmpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rhythmpad design in my own project?
Its repository states no licence, so its author keeps all rights: ask sneakiee before reusing the design.
