Hi user4773354,

The driver hardware has a brake function. I am not certain the firmware uses the brake function.

You mean that you are not sure whether firmware could control the brake function or not? how do we control the brake function?

Hi user4773354,

To control the brake function, typically the 3 low side FETs are enabled.

The PCB is capable of brake mode. The firmware must be written to activate it (not sure if one of the labs has this option).
