About the My pathfinder PCB

My pathfinder is an open source RP2040/RP2350 PCB design by adriel-babalola, published on GitHub. It is a 2-layer board measuring 98.5 × 50.5 mm, with 15 components from 6 distinct parts.

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

From the project

its a modified version of the pathfinder starter project. i added an extra LED, an extra switch, and a buzzer. so now whenever you press a button it makes a sound.

i originally wanted to make a pomodoro timer but honestly it was way too complex for where i was. i kept getting stuck on diagrams i didn't understand and i wasn't making any progress. so i thought, instead of going that deep, why not just take what i know and add something to it. i knew how the switches and LEDs worked from pathfinder already, and making a buzzer sound is literally just a digitalWrite so i added that. its my…

My pathfinder: common questions

What microcontroller does the My pathfinder use?

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

How big is the My pathfinder PCB?

The My pathfinder measures 98.5 × 50.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the My pathfinder?

15 components, from 6 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 My pathfinder design files?

From the adriel-babalola/my-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 My pathfinder design in my own project?

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

Can I test firmware for the My 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.
