Overview
Hackpad is an open-source printed circuit board by thesleepyniko, from the thesleepyniko/numhackpad repository on GitHub. It is a 2-layer board of 112 × 105 mm with 38 parts on 30 nets, routed with 131 tracks and 7 vias.
Its parts include 16 diodes, 16 switches and 1 IC. It belongs with the RP2040 boards of this library.
README
README.mdnumhackpad
numhackpad is a 16 key macropad with nothing else except for cool oneshot art
Features:
- 16 keys
- cool oneshot reference on the pcb
CAD Model:
the case and pcb should fit nicely with 8 m3 screws and heatset inserts. 4 for the case, 4 for the PCB (standoffs).
it has 2 printed pieces: the bottom and the top of the case
made using Fusion360
PCB
heres the pcb, it was made using KiCAD and the silkscreen was taken from a google image of the oneshot lightbulb (no spoilers!)
schematic
pcb
used cherry MX for the footprints
Firmware Overview
numhackpad uses KMK firmware.
- the 16 keys act as a numpad, it is missing the delete key
BOM:
here should be everything you need to make this hackpad
- 16x Cherry MX Switches
- 16x DSA Keycaps
- 8x M3x5x4 Heatset inserts
- 8x M3x16mm screws
- 16x 1N4148 DO-35 Diodes.
- 1x XIAO RP2040
- 1x Case (2 printed parts)
- 1x PCB
Extra stuff
lwk it started off as a normal hackpad and then got a lot worse

Questions
How big is the Hackpad PCB?
It measures 112 × 105 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
38 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 thesleepyniko/numhackpad 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 states no licence, so its author keeps all rights: ask thesleepyniko before reusing the design.
