Overview
Hackpad is an open-source printed circuit board by pakkid, from the pakkid/HexadeciPad repository on GitHub, published under the MIT licence. It is a 2-layer board of 99.3 × 97.6 mm with 27 parts on 37 nets, routed with 255 tracks and 27 vias.
It is built around the SK6812MINI-E. Its parts include 16 switches, 2 resistors, 2 ICs and 2 diodes. It belongs with the RP2040 boards of this library.

Welcome to the HexadeciPad! This README provides an overview of the project, including screenshots, a Bill of Materials (BOM), and additional resources to help you understand and contribute to the project.
Overview
The HexadeciPad is a custom macropad designed as part of the Hackpad limited-time You Ship, We Ship (YSWS) event. I decided to make this Hackpad after realising that my keyboard media controls are kinda trash.
I spent ages trying to create the firmware after not knowing what I was doing. Finally after 20 hours of messing around i ahave finished my Hackpad. The HexadeciPad has 16 total inputs (2x encoder and 14x chery mx switches)
My next steps are probably to create a GUI and button editor app to make it easy to assign custom commands.
Features:
- 16 Inputs!!! you heard me right!
- 2 EC11 Encoders
- 14 Cherry MX Switches
- A janky ahh PCB made by yours truly :3
- Media Controls
- A bunch of app opener keys thingys
- Custom FW (KMK)

Questions
How big is the Hackpad PCB?
It measures 99.3 × 97.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
27 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 pakkid/HexadeciPad repository on GitHub, at the commit this page was made from: the board is pcb/Kicad-Project/hackpad.kicad_pcb and its schematic pcb/Kicad-Project/OPL_Kicad_Library-master/Grove Vision AI V2 Library/Grove - Vision AI Module V2.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 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).
