M2fc: common questions

What microcontroller does the M2fc use?

The M2fc is built around the STM32F405VGT, from the STM32 family.

How big is the M2fc PCB?

The M2fc measures 100 × 70 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the M2fc?

348 components, from 55 distinct parts. The full bill of materials is listed on this page.

Where can I download the M2fc design files?

From the cuspaceflight/m2-electronics repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the M2fc design in my own project?

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

Can I test firmware for the M2fc 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.
