Higher rpm with foc mini 1.1

FOC Mini doesn’t have it, and it’s generally impractical to add as a separate component. But you certainly could try without current sense and see how it does.

I don’t know if there are any readily available micro size boards with current sense. You could check with @rambros if he has any extras of his DRV8316 board you could buy.

I’m also plotting a design with MAX22213 and STM32G431KBU3 which is in the right ballpark.
