About the XIAO PCB

XIAO is an open source RP2040/RP2350 PCB design by Videocraft10, published on GitHub under the MIT license. It is a 2-layer board measuring 203.1 × 125.1 mm, with 21 components from 21 distinct parts.

Its main chip is the XIAO-RP2040-SMD, from the RP2040/RP2350 family. Other key parts include the XIAO-SAMD21-SMD, XIAO-nRF52840-SMD, XIAO-SAMD21-DIP, XIAO-RP2040-DIP and XIAO-nRF52840-DIP.

First download the PCB Gerber file from here then send it to your preferred manufacturer! Next buy all of the components from the BOM. For screws and similar items, it is recommended to find the cheapest in your location. Next 3D print the case from here here and ensure the PCB fits once it arrives. Next solder on all of the components and screw the PCB into the case! Finally flash the firmware onto it from here (you might have to build the file on you own computer)

The KiCad project lives in the Videocraft10/PetPad repository on GitHub; these links point at the commit this page was built from.

XIAO: common questions

What microcontroller does the XIAO use?

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

How big is the XIAO PCB?

The XIAO measures 203.1 × 125.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the XIAO?

21 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the XIAO design files?

From the Videocraft10/PetPad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the XIAO design in my own project?

Yes, under the terms of its MIT license, which Videocraft10 chose for the repository.

Can I test firmware for the XIAO 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.
