Usb3sun: common questions

What microcontroller does the Usb3sun use?

The Usb3sun is built around the C5159530, from the RP2040/RP2350 family.

How big is the Usb3sun PCB?

The Usb3sun measures 35.6 × 94.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Usb3sun?

51 components, from 24 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 Usb3sun design files?

From the delan/usb3sun 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 Usb3sun design in my own project?

Yes, under the terms of its ISC license, which delan chose for the repository.

Can I test firmware for the Usb3sun 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.
