Usbc pal: common questions

What microcontroller does the Usbc pal use?

The Usbc pal is built around the STM32F072C8Ux, from the STM32 family.

How big is the Usbc pal PCB?

The Usbc pal measures 76.2 × 15.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Usbc pal?

33 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Usbc pal design files?

From the jessfraz/usbc-pal repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Usbc pal design in my own project?

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

Can I test firmware for the Usbc pal without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
