About the Hackpad PCB

Hackpad is an open source RP2040/RP2350 PCB design by haohaohaoyan, published on GitHub. It is a 2-layer board measuring 100 × 71.4 mm, with 10 components from 4 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. By type, the board carries 8 switches, 1 IC and 1 connector.

It belongs with the keyboards and displays & leds designs in this gallery.

From the project

hackpad for blueprint, design schematics here

a small macropad for hack club's blueprint. it has a screen for a keys-per-second tracker (and maybe bad apple in the future), four keys for rhythm games, a rotary encoder for volume, and prev/pause/next track buttons.

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 100 × 71.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hackpad?

10 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hackpad design files?

From the haohaohaoyan/hackpad repository on GitHub, which has the KiCad layout and the schematic; 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 haohaohaoyan. 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.
