Besc hw: common questions

What microcontroller does the Besc hw use?

The Besc hw is built around the STM32F40X_LQFP64, from the STM32 family.

How big is the Besc hw PCB?

The Besc hw measures 39.9 × 97.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Besc hw?

120 components, from 44 distinct parts. The full bill of materials is listed on this page.

Where can I download the Besc hw design files?

From the augustbering/besc-hw repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Besc hw design in my own project?

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

Can I test firmware for the Besc hw 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.
