About the Pxlboard PCB

Pxlboard is an open source RP2040/RP2350 PCB design by taciturnaxolotl, published on GitHub under the MIT license. It is a 2-layer board measuring 72.8 × 83.8 mm, with 79 components from 9 distinct parts.

Its main chip is the XIAO-RP2040-SMD, from the RP2040/RP2350 family. Other key parts include the LIS3DHTR. By type, the board carries 64 diodes, 12 capacitors, 2 ICs and 1 connector.

Pxlboard: common questions

What microcontroller does the Pxlboard use?

The Pxlboard is built around the XIAO-RP2040-SMD, from the RP2040/RP2350 family.

How big is the Pxlboard PCB?

The Pxlboard measures 72.8 × 83.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pxlboard?

79 components, from 9 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 Pxlboard design files?

From the taciturnaxolotl/pxlboard 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 Pxlboard design in my own project?

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

Can I test firmware for the Pxlboard 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.
