About the Hackpad PCB

Hackpad is an open source RP2040/RP2350 PCB design by Gabouin, published on GitHub under the MIT license. It is a 2-layer board measuring 95 × 62 mm, with 22 components from 6 distinct parts.

Its main chip is the MOUDLE-SEEEDUINO-XIAO, from the RP2040/RP2350 family. By type, the board carries 13 diodes, 7 switches, 1 IC and 1 connector.

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

From the project

my first PCB project : a simple hackpad with 6 switches, a rotary encoder, an oled display and the microcontroller.

This is my first PCB project : a simple macropad with 6 switches, a rotary encoder, an oled display and a microcontroller. The OLED screen will display animations based on what switch is pushed, leds will be illuminating the whole macropad with predifined colors animations. The rotary encoder is going to be used to change the volume and to change the key shortcuts mode by clicking it. The switches will either regulate my spotify playlist (first key shortcut mode) or other shortcuts based on what work I complete.

Hackpad: common questions

What microcontroller does the Hackpad use?

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

How big is the Hackpad PCB?

The Hackpad measures 95 × 62 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hackpad?

22 components, from 6 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 Gabouin/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?

Yes, under the terms of its MIT license, which Gabouin chose for the repository.

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.
