Looks like someone has made a commercial product based on this controller. Check out ebay item # 252952728174
I would post a pic and link but my post count is too low for that.

The layout is similar, but there aren't that many possible layouts anyway. It's impressive that they can do a commercial product for $265. I guess bulk electronics and getting metals made in bulk really drives the price down. They don't do torque control, so I'm not sure how it would feel in a car. Maybe like a curtis or something. It's impressive how a final product can look when you don't do everything in your garage. lol

I didn't see the processor ... are they using the same one? Perhaps upgraded your code?
Or did they do their own thing?

I think they used an STM32F0, so the software is probably based on their own stuff. I am trying to learn the stm32 right now. It's so heartbreaking. They have tools like the CubeMX, which is a big buggy bloatware thing that autogenerates like 100,000 lines of code just to blink an LED. I would literally trade my pinky for someone to make a simple microcontroller that lets you do hardware floating point, and then they get the heck out of the way.

fwiw, there is the stm gcc-arm-none-eabi toolchain, like johannes uses:
https://github.com/jsphuebner/stm32-sine though it is linux centric, I've compiled his code w/it before.

Just a bump
I found most of the stuff that I think vivek needs. But I don't seem to have the gerber files for the power board.
Anyone else have backups to share?

@MPaulHolmes, im a college teacher, teaching electronics, microcontrollers and VHDL.
This past year i had 4 student teams building EV drivers loosely based on yours, as their graduate project.
so i wanted to thank you for keep passing the knowledge.
