Vesc2: common questions
What microcontroller does the Vesc2 use?
The Vesc2 is built around the STM32G474_VESC, from the STM32 family.
How big is the Vesc2 PCB?
The Vesc2 measures 37 × 62 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the Vesc2?
123 components, from 47 distinct parts. The full bill of materials is listed on this page.
Where can I download the Vesc2 design files?
From the bluesatunsw/owr repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Vesc2 design in my own project?
Yes, under the terms of its Apache-2.0 license, which bluesatunsw chose for the repository.
Can I test firmware for the Vesc2 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.
