F3fc: common questions

What microcontroller does the F3fc use?

The F3fc is built around the STM32F303x{B,C}, from the STM32 family.

How big is the F3fc PCB?

The F3fc measures 36 × 36 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the F3fc?

49 components, from 36 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 F3fc design files?

From the chickadee-tech/f3fc repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the F3fc design in my own project?

Yes, under the terms of its CC-BY-4.0 license, which chickadee-tech chose for the repository.

Can I test firmware for the F3fc 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.
