README.mdrandompad
randompad is @randomhumandownhere 's submission to the Hackpad YSWS. it has 9 keys, 16 WS2812B LEDs and a 0.91in SSD1306 OLED display (fancy graphics!) as well as an EC11 rotary encoder. it uses KMK firmware too.
features
- really simple 3d printed case
- 128x32 OLED display
- 16 WS2812B LEDs
- 9 MX style keys
- and an EC11 rotary encoder!
cad model!
it uses 4 M3 bolts and heatset inserts to hold it together
pcb and schematics!
notes?
i'll probably make a better, more polished one in the future with more features

Questions
How big is the Randompad pcb PCB?
It measures 71.4 × 88.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Randompad pcb use?
41 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 Randompad pcb KiCad files?
From the randomhumandownhere/randompad repository on GitHub, at the commit this page was made from: the board is pcb/randompad_pcb.kicad_pcb and its schematic pcb/randompad_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Randompad pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask randomhumandownhere before reusing the design.
