M4pyro: common questions

What microcontroller does the M4pyro use?

The M4pyro is built around the STM32F405RxTx, from the STM32 family.

How big is the M4pyro PCB?

The M4pyro measures 100 × 74.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the M4pyro?

165 components, from 45 distinct parts. The full bill of materials is listed on this page.

Where can I download the M4pyro design files?

From the cuspaceflight/m4-avionics repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the M4pyro 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 M4pyro 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.
