STM32F4surface: common questions

What microcontroller does the STM32F4surface use?

The STM32F4surface is built around the STM32F103RET6, from the STM32 family.

How big is the STM32F4surface PCB?

The STM32F4surface measures 25.5 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the STM32F4surface?

28 components, from 19 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 STM32F4surface design files?

From the profdc9/STM32F4surface repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the STM32F4surface design in my own project?

The repository has no license, so all rights stay with profdc9. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the STM32F4surface 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.
