Overview
Pixelpad is an open-source printed circuit board by PixelSaver, from the PixelSaver/pixelpad repository on GitHub, published under the MIT licence. It is a 2-layer board of 61.5 × 55.5 mm with 18 parts on 22 nets, routed with 98 tracks and 7 vias.
It is built around the SK6812MINI-E. Its parts include 8 diodes, 6 switches, 1 IC and 1 connector.

PixelPad is a 5 key macropad with a rotary encoder, an OLED screen, and two LEDs. It's my first piece of hardware I've ever made (I don't count building a pc), so I'm really excited to use seomthing made by me. I tried to make it as compact as possible while still fitting everything.
It was made for the Hackclub organization's Hackpad YSWS. I took major inspiration from the example OrpheusPad, so check that project out too!
Features
- 128x32 OLED Display
- EC11 Rotary encoder for (probably) Volume
- 2 WS2812B RGB LEDs. Both are at the top right to signify the mode / power / whatever other info is needed
- 5 Keys
- Hopefully VIA Support!
Cad Model
Everything bolts together using 5 M3 bolts (one of the bolts isn't 16, its 12 which will need some cutting once it gets shipped). The bottom of the case makes a 5 degree tilt so that the screen is easier read.
Printed in 4 separate pieces, the bottom case, the switch plate in the middle, the top cover, and a knob.
Made in OnShape!! Screw Fusion360 and their predatory pricing tactics!
PCB
Made using KiCad, here's the pcb and schematics for everything.

Firmware
The macropad uses QMK for its firmware. I still haven't wrapped my head around how that works, and I plan to tinker once I build it.
For now, I can pray that the features are there, and that I can run some code for the OLED for a clock or music playing.

Questions
How big is the Pixelpad PCB?
It measures 61.5 × 55.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pixelpad use?
18 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 Pixelpad KiCad files?
From the PixelSaver/pixelpad repository on GitHub, at the commit this page was made from: the board is pcb/pixelpad.kicad_pcb and its schematic pcb/pixelpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pixelpad design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
