About the Pcb

Pcb is an open source RP2040/RP2350 PCB design by sanoojes, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 100 × 84 mm, with 49 components from 5 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. By type, the board carries 16 switches, 16 LEDs, 16 diodes and 1 IC.

It belongs with the keyboards designs in this gallery.

From the project

My project for Hackclub Blueprint

A simple, customizable macropad with hot swapable keys, fully programmable keys, per-key RGB lighting, multiple profiles for gaming, programming, editing, and more. uses QMK Firmware

Firmware available at firmware/ firmware will be tweaked and updated after i get the materials.

- 1x XIAO_RP2040 module - 1x SK6812 Mini LEDs - 1x EC11 Rotary Encoder - 4x M3x16mm screws - 4x M3x5mmx4mm inserts - 16x Cherry MX Hotswappable Switches - 16x DSA Keycaps - 3D Printed Case

Pcb: common questions

What microcontroller does the Pcb use?

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

How big is the Pcb?

The Pcb measures 100 × 84 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pcb?

49 components, from 5 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 Pcb design files?

From the sanoojes/hackclub-bitpad 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 Pcb design in my own project?

Yes, under the terms of its GPL-3.0 license, which sanoojes chose for the repository.

Can I test firmware for the Pcb 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.
