Overview
Hackpad is an open-source printed circuit board by SebbyMortimer, from the SebbyMortimer/hackpad repository on GitHub. It is a 2-layer board of 62.7 × 55.5 mm with 8 parts on 16 nets, routed with 53 tracks and 3 vias.
It is built around the SK6812MINI-E. Its parts include 4 switches, 2 diodes, 1 IC and 1 connector. It belongs with the RP2040 boards of this library.

README.mdSebby's Hackpad
My personal hackpad for being a power user and probably do something funny. It has 4 buttons, 2 LEDs and an OLED panel.
This is my second time creating a PCB (my first was the "blinky" LED chaser) so I'm still heavily relying on the guide to get me a working macropad, but I was able to add an OLED panel to it with some help from the Hack Club Slack community. I have worked with CAD software a lot in school and we use Autodesk Inventor instead of Fusion 360 so that's why I used Inventor when creating the case, it was a pretty similar process though.
BOM:
- 1x Seeed XIAO RP2040
- 4x MX-Style switches
- 1x 0.91 inch OLED display
- 4x Blank DSA keycaps (White)
- 2x SK6812 MINI-E LEDs
- 4x M3x16mm screws
- 4x M3x5mx4mm heatset inserts

Questions
How big is the Hackpad PCB?
It measures 62.7 × 55.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
8 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 Hackpad KiCad files?
From the SebbyMortimer/hackpad repository on GitHub, at the commit this page was made from: the board is PCB/hackpad.kicad_pcb and its schematic PCB/hackpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpad design in my own project?
Its repository states no licence, so its author keeps all rights: ask SebbyMortimer before reusing the design.
