Description
This repository has all CAD files for the Phyduino Pico board used in the University of Toronto, Department of Physic, "Introduction to Electronics course."
This board is used to train graduate students first and foremost in surface mount hole solder techniques. As part of the training in the course they will as learn digital interfaces and digital IO design methods as well. This board is a fully function Arduino Uno style board using the Raspberry PI RP2040 microcontroller.
The CAD program used to design this board is KiCAD which open source and free to use. The Interactive Html BoM plugin was used to generate the interactive bill of materials html file.
Files
- Gerber Files are located in the fabrication folder
- There is an Interactive bill of materials html file that you can use to assist you in assembling the board.

Questions
How big is the Phyduino pico PCB?
It measures 68.6 × 53.3 mm and has 4 copper layers, 1.58 mm thick.
What parts does the Phyduino pico use?
129 parts, built around the RP2040, MAX11635EEE+T, TPS2121RUXT and USBLC6-2P6. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Phyduino pico KiCad files?
From the perc-sw/phyduino_pico repository on GitHub, at the commit this page was made from: the board is phyduino_pico.kicad_pcb and its schematic phyduino_pico.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Phyduino pico design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
