Overview
Hackpad PCB is an open-source printed circuit board by meowlery, from the meowlery/My-PP repository on GitHub, published under the MIT licence. It is a 2-layer board of 89 × 69 mm with 12 parts on 16 nets, routed with 109 tracks and 0 vias.
It is built around the SK6812MINI-E. Its parts include 9 switches, 2 diodes and 1 IC. It belongs with the keyboards and input boards and the RP2040 boards of this library.

README.mdMy PP
“My PP” is a macropad that I designed with 9 keys. PP stands for “Personal Pad,” since it has my personal features that I use most. You probably noticed that it’s a reference to “PC,” which stands for “Personal Computer” (; (i know it's very random).
Notes:
I built this macropad using a Hack Club tutorial, and it was really fun. Here is how the final product will look like after building the parts together:
Challenges:
With designing this macropad, I learned many things, which was really cool. For example, I designed a PCB for the first time! I already have an Arduino with a breadboard for some small projects, and I wondered many times about how to design a PCB but thought it was way more difficult than it actually is. And I created for the first time something in 3D with Fusion360.
Programs I used:
- Fusion360 for CAD
- KiCad for the PCB
- QMK Firmware for the firmware (did I need to explain it?)
BOM:
Here are the things that are inside my macropad:
- 4x M3 Heatset
- 4x M3x16 Bolt
- 4x Blank DSA Keycaps
- 1x XIAO RP2040
- 2x SK6812 MINI Leds
- 9x Cherry MX Switches

Questions
How big is the Hackpad PCB PCB?
It measures 89 × 69 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad PCB use?
12 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 PCB KiCad files?
From the meowlery/My-PP repository on GitHub, at the commit this page was made from: the board is PCB/Hackpad PCB.kicad_pcb and its schematic PCB/Hackpad PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpad PCB 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).
