About the Boardsmith PCB

Boardsmith is an open source RP2040/RP2350 PCB design by ForestHubAI, published on GitHub under the AGPL-3.0 license. It is a board, with 37 components from 19 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the SCD41, SSD1306, BME680, W25Q16JVSSIQ and AMS1117-3.3. By type, the board carries 15 capacitors, 12 resistors, 6 ICs, 2 connectors, 1 transistor and 1 crystal.

It belongs with the sensors designs in this gallery.

From the project

Text prompt → KiCad schematic, BOM, and firmware. No templates — real wired circuits with computed values.

Works on Mac, Windows, and Linux. Requires Python 3.10+.

Why this exists · Install · Examples · How it works · Contributing

Designing a circuit today means: open KiCad, manually place components, look up datasheets for every pull-up value, voltage divider, and decoupling cap. Miss one constraint and the board doesn't work. Every hobby project starts with hours of busywork before you write a single line of firmware.

Boardsmith: common questions

What microcontroller does the Boardsmith use?

The Boardsmith is built around the RP2040, from the RP2040/RP2350 family.

How many components are on the Boardsmith?

37 components, from 19 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 Boardsmith design files?

From the ForestHubAI/boardsmith repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

Can I use the Boardsmith design in my own project?

Yes, under the terms of its AGPL-3.0 license, which ForestHubAI chose for the repository.

Can I test firmware for the Boardsmith 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.
