@Davewesh is correct here and swapping out for the DRV8353 isn’t arbitrary. I designed a whole different controller around it called the Little FOCer. It’s a more premium product that’s not geared for open hardware and DIY like the CFOC2 is. However, praise the day if/when JLCPCB supports the DRV8353 in its SMT service or even the DRV8323.
Trying to increase the operating voltage with the CFOC2 design will result in it being larger and/or more expensive. The higher the voltage rating of the components, the more they cost.
