Woodchuck: common questions

What microcontroller does the Woodchuck use?

The Woodchuck is built around the STM32F072CBT6, from the STM32 family.

How big is the Woodchuck PCB?

The Woodchuck measures 58 × 35 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Woodchuck?

38 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Woodchuck design files?

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

Can I use the Woodchuck design in my own project?

Yes, under the terms of its MIT license, which cuspaceflight chose for the repository.

Can I test firmware for the Woodchuck 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.
