About the Pathfinder PCB

Pathfinder is an open source RP2040/RP2350 PCB design by bangzishu-huang, published on GitHub under the MIT license. It is a 2-layer board measuring 101.5 × 34.4 mm, with 13 components from 4 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. By type, the board carries 4 switches, 4 diodes, 4 resistors and 1 IC.

From the project

I will be making a cool little pathfinder.

Cool little side project I decided to pick up. This would be an amazing fidget toy I can keep at the edge of my desk!

Pathfinder: common questions

What microcontroller does the Pathfinder use?

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

How big is the Pathfinder PCB?

The Pathfinder measures 101.5 × 34.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pathfinder?

13 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pathfinder design files?

From the bangzishu-huang/Pathfinder repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Pathfinder design in my own project?

Yes, under the terms of its MIT license, which bangzishu-huang chose for the repository.

Can I test firmware for the Pathfinder 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.
