README
README.mdHalpad
Halpad is a 9 key macropad with a knob and OLED designed around the idea of quickly selecting features.
Features:
- Simplistic case design
- 128x32 OLED Display
- EC11 Rotary encoder
- 9 Switches
CAD Model:
For the case, only M3x16mm and M3 heatset inserts are used for hardware, allowing for a simple BOM. It also only uses 3 3d printed parts for assembly, allowing for a quick and straightforward build.
Made in Fusion

Firmware:
This macropad uses KMK firmware currently, with plans to use QMK in the future.
BOM:
- 9x Cherry MX Switches
- 9x Keycaps (whatever profile, designed around standard spacing)
- 4x M3x5x4 Heatset Inserts
- 4x M3x16mm SHCS Bolts
- 10x 1N4148 DO-35 Diodes
- 1x 0.91" 128x32 OLED Display
- 1x EC11 Rotary Encoder
- 1x XIAO RP2040
- 1x Case (3 printed parts)

Questions
How big is the Hackpad PCB?
It measures 95.3 × 61.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
22 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 Hackpad KiCad files?
From the Automationman1/Halpad 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 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).
