A music application UI Macropad
Purpose
I made this macropad for Hack Club's Highway using their Hackpad Tutorial. It's meant to be used as an accompaniment to music applications, primarily Youtube Music (which I use), as a physical UI. I like to listen to music
Features
- An OLED meant to display info such as:
- Song name/duration
- Whether song is played/paused
- Whether shuffle or loop (playlist or song) is on
- More ideas in the future if I come up with any :)
- A rotary encoder switch that changes the volume and mutes the music application when pressed
- Keys for rewind/prev track, play/pause, fast forward/next track, loop, and shuffle
- A Mini-E LED which, for now, is meant to serve as an indicator that the macropad is on
- QMK Firmware

Questions
How big is the MusicPad PCB?
It measures 65.1 × 65.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MusicPad use?
15 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 MusicPad KiCad files?
From the fatchickenugget/MusicPad repository on GitHub, at the commit this page was made from: the board is pcb/MusicPad.kicad_pcb and its schematic pcb/Libraries/OPL_Kicad_Library-master/Grove Vision AI V2 Library/Grove - Vision AI Module V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MusicPad design in my own project?
Its repository states no licence, so its author keeps all rights: ask fatchickenugget before reusing the design.
