STM32F072xB: common questions

What microcontroller does the STM32F072xB use?

The STM32F072xB is built around the STM32F072C8T6, from the STM32 family.

How big is the STM32F072xB PCB?

The STM32F072xB measures 82.3 × 32.8 mm, has 4 copper layers and is 1.647165 mm thick.

How many components are on the STM32F072xB?

49 components, from 33 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 STM32F072xB design files?

From the zOnlyKroks/pcb-consortium 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 STM32F072xB design in my own project?

Yes, under the terms of its CC0-1.0 license, which zOnlyKroks chose for the repository.

Can I test firmware for the STM32F072xB 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.
