Vesc: common questions

What microcontroller does the Vesc use?

The Vesc is built around the STM32F405RGTx, from the STM32 family.

How big is the Vesc PCB?

The Vesc measures 61.5 × 60 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Vesc?

196 components, from 66 distinct parts. The full bill of materials is listed on this page.

Where can I download the Vesc design files?

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

Can I use the Vesc design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which LJBoxx chose for the repository.

Can I test firmware for the Vesc 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.
