myfirsthackpad is a space themed 3 key macropad with 5 SK6812 MINI-E LEDs.
It is used as a media playback controller to go back, pause, and go next.
Features:
- 3 Keys
- 5 SK6812 MINI-E LEDs (3 for underglow and 2 that just glow)
CAD Model:
Everything fits together using 5 M3 Bolts and heatset inserts. 4 for the case, one for the PCB.
It has 2 separate printed pieces: the base where the PCB sits, and the top cover.
This was made in Onshape.

Questions
How big is the Myfirsthackpad PCB?
It measures 64 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Myfirsthackpad use?
11 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 Myfirsthackpad KiCad files?
From the eltonchan1/myfirsthackpad repository on GitHub, at the commit this page was made from: the board is pcb/myfirsthackpad.kicad_pcb and its schematic pcb/myfirsthackpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Myfirsthackpad design in my own project?
Its repository states no licence, so its author keeps all rights: ask eltonchan1 before reusing the design.
