About the Hackpad PCB

Hackpad is an open source RP2040/RP2350 PCB design by jirachi123, published on GitHub. It is a 2-layer board measuring 81 × 43.6 mm, with 7 components from 3 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. By type, the board carries 4 switches, 2 diodes and 1 IC.

It belongs with the keyboards designs in this gallery.

From the project

4-key macropad for highway. Made it to use for media controls as I use a 65% keyboard and don't have easily accessible media buttons. Might be used to play osu or other rhythm games.

Hackpad: common questions

What microcontroller does the Hackpad use?

The Hackpad is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.

How big is the Hackpad PCB?

The Hackpad measures 81 × 43.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hackpad?

7 components, from 3 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Hackpad design files?

From the jirachi123/hackpad repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Hackpad design in my own project?

The repository has no license, so all rights stay with jirachi123. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Hackpad without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
