A macro-pad with 16 keys and a rotary encoder powered by Seeed XIAO RP2040
I wanted something that was actually useful on my desk, but also something I could completely customize so i made this from the PCB and firmware to the case.
Things present in the chaox-pad
- 16 MX-style mechanical switches
- 1 EC11 rotary encoders
- Seeed XIAO RP2040
- 1N4148 diodes
- Custom PCB
- Custom 3D-printed case
- CHAOX engraved top plate
The design
I designed this case in FreeCAD.
I kept the top plate removable, so the switches and electronics can be assembled more easily.
PCB
I used Kicad 10 to make my PCB
The PCB files are in:
PCB/
Firmware
The firmware is written using KMK and CircuitPython.
It currently includes:
- Multiple layers
- Keyboard shortcuts
- Text macros
- Numpad layer
- Rotary encoder controls
- Volume controls
- Tab switching
- Media controls
Firmware files are in:
Firmware/
CAD files
All of the case files are available in:
CAD/
You can open the FreeCAD file if you want to modify the design yourself.
The STEP files are also included for anyone who wants to work with the case in another CAD program.

Why I made it
I wanted to build something but didn't know what to build so then i saw a reel of alex saying i made this hackpad and u can build it too so i got inspired and made this.
There will probably be things I change in the future, but this is the current version of the Chaox-Macropad

Questions
How big is the Freaky 2 PCB?
It measures 80 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Freaky 2 use?
35 parts. 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 Freaky 2 KiCad files?
From the 01HACKER01/CHAOX-Macropad repository on GitHub, at the commit this page was made from: the board is PCB/freaky 2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Freaky 2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask 01HACKER01 before reusing the design.
