About the Hackpad PCB

Hackpad is an open source RP2040/RP2350 PCB design by newtontriumphant, published on GitHub. It is a 2-layer board measuring 91 × 40.3 mm, with 9 components from 4 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. By type, the board carries 7 switches, 1 IC and 1 diode.

It belongs with the keyboards designs in this gallery.

From the project

HackPad built for HackClub's Blueprint Program. Fully Modular, with 6 Cherry MX-Style Switch Ports, 1 Rotary Encoder, and 1 Mini RGB LED.

Fun Fact: This was my first time creating a serious project in KiCad! I think it turned out quite well, took some time but it was worth it! Hopefully it works :)

UPDATE: Gerber file ZIP added to PCB folder.

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 91 × 40.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hackpad?

9 components, from 4 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 newtontriumphant/zsharpminor-hackpad-v-1-2-FINAL 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 newtontriumphant. 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.
