USB: common questions

What microcontroller does the USB use?

The USB is built around the 10164227-1001A1RLF, from the Raspberry Pi family.

How big is the USB PCB?

The USB measures 70 × 60 mm, has 4 copper layers and is 1.517 mm thick.

How many components are on the USB?

23 components, from 15 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 USB design files?

From the SPIRIT-org/USB-test 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 USB design in my own project?

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

Can I test firmware for the USB without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
