Boardstorm x3: common questions

What microcontroller does the Boardstorm x3 use?

The Boardstorm x3 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Boardstorm x3 PCB?

The Boardstorm x3 measures 21 × 51 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Boardstorm x3?

48 components, from 26 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 Boardstorm x3 design files?

From the shashwtd/boardstorm-x3 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 Boardstorm x3 design in my own project?

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

Can I test firmware for the Boardstorm x3 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.
