How much of a voltage drop do these BLDC motor drivers have?

I don’t see that information listed anywhere on these product pages:

pololu.com/product/0713
pololu.com/product/2130

It’s important since some drivers drop several volts (i.e. you give it VCC volts, but the motors get VCC-Vdrop volts).

Hello.

These motor drivers are not for brushless DC motors. Also, I am not sure what you are asking about the voltage drop. Both of those motor drivers can modulate between 0 and VIN/VMOT. For more information, you can refer to the drivers’ datasheets, which can be found under the “Resources” tab on their respective product pages.
