Goals:
The original Vesc design is very good for the things it wants to do. I want to do different things and still be able to use the same firmware. So I made this version.
The idea was that I only wanted to drive very weak motors. So this version is cheap and not that good. :man_shrugging:

Questions
How big is the BLDC 4 PCB?
It measures 82 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BLDC 4 use?
99 parts, built around the DRV8302 and SI2302CDS. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the BLDC 4 KiCad files?
From the koson/bldc_hardware-1 repository on GitHub, at the commit this page was made from: the board is design/BLDC_4.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BLDC 4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask koson before reusing the design.
