Uswc: common questions

What microcontroller does the Uswc use?

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

How big is the Uswc PCB?

The Uswc measures 27.5 × 24 mm, has 2 copper layers and is 0.8 mm thick.

How many components are on the Uswc?

44 components, from 29 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 Uswc design files?

From the crides/uswc 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 Uswc design in my own project?

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

Can I test firmware for the Uswc 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.
