STM32G0F6Px-ROC: common questions

What microcontroller does the STM32G0F6Px-ROC use?

The STM32G0F6Px-ROC is built around the STM32G030F6Px, from the STM32 family.

How big is the STM32G0F6Px-ROC PCB?

The STM32G0F6Px-ROC measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the STM32G0F6Px-ROC?

53 components, from 26 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 STM32G0F6Px-ROC design files?

From the oxfordfish/STM32G0F6Px-ROC 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 STM32G0F6Px-ROC design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which oxfordfish chose for the repository.

Can I test firmware for the STM32G0F6Px-ROC 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.
