This repository contains all files for my AMD x HackClub Macropad project.
The macropad is designed for computer shortcuts, python programming, and game controlling.
It features:
- 3x3 mechanical keys
- 0.91" OLED display
- Powered by a Seeed XIAO RP2040 microcontroller

This is the overview of my hackpad assembled in Fusion 360 which shows how it should be all put together
This is my schematic that I designed in KiCad showing which components I'm using and how they are connected. As you can see, each key switch is wired seperately to the RP2040 and the OLED is orded in GND-VCC-SCL-SDA so that it is compatible with the 0.91" display sent by HackClub
This is my PCB layout that I designed in the KiCad PCB Designer. It shows all of the component placement and copper wiring so I can visualise all the connections. I also added some customisation on the silkscreen such as a link to this github repository & the name of my Hackpad
I designed the base & cover in Fusion 360 using the measurements from my PCB in KiCad, and I imported all the 3D models in to test-fit all of them together
List of all parts used in my hackpad:
| Part | Quantity | Description |
|---|---|---|
| Mechanical Key Switches | 9 | MX-style switches |
| Cherry Keycaps | 9 | Compatible with MX switches |
| Seeed XIAO RP2040 | 1 | Microcontroller |
| OLED Display 0.91" | 1 | I2C interface |
| PCB | 1 | Double-sided |
| Case | 1 | 3D printed (prob PLA) |
- Download & install CircuitPython .uf2
- Connect the Seeed XIAO RP2040 via USB and enter bootloader mode
- Flash the MCU with the .uf2
Libraries:
- Download CircuitPython library bundle & unzip
- Copy displayio, display_text, debouncer & HID to the MCU
- Upload the
code.pyto the XIAO - Test
