WolffNest-STM32-board: common questions

What microcontroller does the WolffNest-STM32-board use?

The WolffNest-STM32-board is built around the STM32U575VGT6, from the STM32 family.

How big is the WolffNest-STM32-board?

The WolffNest-STM32-board measures 49.3 × 35.7 mm, has 4 copper layers and is 1.48 mm thick.

How many components are on the WolffNest-STM32-board?

40 components, from 18 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 WolffNest-STM32-board design files?

From the Wolffyx/WolffNest-STM32-board repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the WolffNest-STM32-board design in my own project?

Yes, under the terms of its Apache-2.0 license, which Wolffyx chose for the repository.

Can I test firmware for the WolffNest-STM32-board 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.
