Overview
Launchpad is an open-source printed circuit board by aarush4code, from the aarush4code/launchpad repository on GitHub. It is a 2-layer board of 86 × 90.3 mm with 13 parts on 22 nets, routed with 113 tracks and 5 vias.
It is built around the SK6812. Its parts include 6 diodes, 6 switches and 1 IC. It belongs with the keyboards and input boards and the RP2040 boards of this library.
Main components
1README
README.mdI created a macropad, that can:
- higher and lower the volume
- copy and paste
- enter
- pause.
Whilecreating this, I learned how to wire, route, and CAD things in Fusion360. This project has been very fun as making a macropad in something I have never done before.

Questions
How big is the Launchpad PCB?
It measures 86 × 90.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Launchpad use?
13 parts, built around the 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 Launchpad KiCad files?
From the aarush4code/launchpad repository on GitHub, at the commit this page was made from: the board is pcb/Launch pad.kicad_pcb and its schematic pcb/Launch pad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Launchpad design in my own project?
Its repository states no licence, so its author keeps all rights: ask aarush4code before reusing the design.
