Features
- Microcontroller: Seeed Studio XIAO.
- Inputs: 4 direct-wired MX mechanical key switches + 1 rotary encoder with integrated push switch.
- Firmware: KMK Firmware on CircuitPython for drag-and-drop keymap edits.
- CAD: Sandwich design consisting of a 3D-printed top cover, main base, column and a laser-cut acrylic "window" Assembled using M3 standoffs and machine screws. Note: the "column" is not attached to the top because it is 3D printed - it will be attached separately
- PCB: Designed in Kicad (Also see PCB above):

Keymaps
- Encoder: Rotate for Previous/Next Track; Press for Play/Pause.
- SW1, SW2, SW3: Undo (
Ctrl+Z), Copy (Ctrl+C), Paste (Ctrl+V). - I might later add multiple key command layers.

Questions
How big is the Hackpad2 PCB?
It measures 80.6 × 41.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad2 use?
7 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 Hackpad2 KiCad files?
From the lima6-tech/Hackpad2 repository on GitHub, at the commit this page was made from: the board is PCB/Hackpad2.kicad_pcb and its schematic PCB/Hackpad2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpad2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask lima6-tech before reusing the design.
