Overview
Mini keyboard 2 is an open-source printed circuit board by anton2785-bit, from the anton2785-bit/Anton-s-Hackpad repository on GitHub. It is a 2-layer board of 98.5 × 40.6 mm with 13 parts on 19 nets, routed with 161 tracks and 5 vias.
It is built around the SK6812MINI-E. Its parts include 9 switches, 3 diodes and 1 IC. It belongs with the keyboards and input boards and the RP2040 boards of this library.

Other non standard ( project specific ) parts
- Custom PCB
-
- Custom schematic
-
- 3D‑printed case (top & bottom)
-
Case & Mounting
- The case is fully 3D‑printed
- Heat‑set inserts are installed into the case for durability
- PCB is mounted directly to the case
Ensure heat‑set inserts are installed carefully using a soldering iron tip sized for M3 inserts.
Assembly Notes
- Solder all components to the PCB
- Place the PCB in the case and screw the top plate
- Attach keycaps
Firmware
- I used KMK for this project, but ill improve it when i get the hackpad
Perfect for:
- Coding shortcuts
- CAD
- Learning keyboard firmware

Questions
How big is the Mini keyboard 2 PCB?
It measures 98.5 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mini keyboard 2 use?
13 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 Mini keyboard 2 KiCad files?
From the anton2785-bit/Anton-s-Hackpad repository on GitHub, at the commit this page was made from: the board is PCB/mini keyboard 2.kicad_pcb and its schematic PCB/mini keyboard 2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mini keyboard 2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask anton2785-bit before reusing the design.
