VESC-6: common questions
What microcontroller does the VESC-6 use?
The VESC-6 is built around the STM32F40X_LQFP64, from the STM32 family.
How big is the VESC-6 PCB?
The VESC-6 measures 62 × 60 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the VESC-6?
143 components, from 70 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 VESC-6 design files?
From the veazhang/VESC-6 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the VESC-6 design in my own project?
The repository has no license, so all rights stay with veazhang. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the VESC-6 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.
