About the Pathfinder PCB

Pathfinder is an open source RP2040/RP2350 PCB design by Anycircle11139s, published on GitHub. It is a 2-layer board measuring 43.5 × 61.5 mm, with 10 components from 4 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. By type, the board carries 3 switches, 3 diodes, 3 resistors and 1 IC.

From the project

This is the schematic, I found this fairly easy, and quickly moved on to the PCB.

This is my PCB, I arranged the parts and routed them. I spent a while creating the edge.cuts.

This is my 3d model, I spent the longest time doing this, the CAD was just really tedious.

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 43.5 × 61.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pathfinder?

10 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 Anycircle11139s/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?

The repository has no license, so all rights stay with Anycircle11139s. Use it as a reference, and ask the author before reusing the design.

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.
