About the Pathfinder PCB

Pathfinder is an open source RP2040/RP2350 PCB design by llxmxx, published on GitHub. It is a 2-layer board measuring 73 × 42 mm, with 15 components from 4 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. By type, the board carries 5 diodes, 5 resistors, 4 switches and 1 IC.

It belongs with the keyboards designs in this gallery.

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 73 × 42 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pathfinder?

15 components, from 4 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 Pathfinder design files?

From the llxmxx/pathfinder 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 Pathfinder design in my own project?

The repository has no license, so all rights stay with llxmxx. 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.
