Hackpad is an open-source printed circuit board by KavEn06, from the KavEn06/MultiPad repository on GitHub. It is a 2-layer board of 90.8 × 63.1 mm with 10 parts on 14 nets, routed with 81 tracks and 0 vias.
Its parts include 6 switches, 1 IC and 1 connector. It belongs with the RP2040 boards of this library.
The CAD model is held together with 4 M3 screws and heatset inserts. It’s built in three layers: the bottom layer holds all the components, the middle layer keeps the switches in place, and the top layer is mainly there to look nice.
| Case | Layers |
|---|---|
The CAD model was made in OnShape.
Here's the PCB! It utilizes a XIAO RP2040, which is connected to 6 switches, a 128x32 OLED display, and an EC11 rotary encoder.

It measures 90.8 × 63.1 mm and has 2 copper layers, 1.6 mm thick.
10 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.
From the KavEn06/MultiPad 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.
Its repository states no licence, so its author keeps all rights: ask KavEn06 before reusing the design.
