USB bga: common questions

What microcontroller does the USB bga use?

The USB bga is built around the STM32G474RET3, from the STM32 family.

How many components are on the USB bga?

12 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the USB bga design files?

From the mrPuckk/USB_bga repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the USB bga design in my own project?

Yes, under the terms of its MIT license, which mrPuckk chose for the repository.

Can I test firmware for the USB bga 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.
