Hello all,
I would like to understand the key differences between the two controllers and which one would better suit my needs.
I want to precisely control the speed of two sensorless bldc motors, keeping them in sync regardless of the load each of those is experiencing.
Thanks, regards

Hi @Hannibal and welcome to the ST Community !
Both boards operate with a battery pack from 3S to 6S Li-Po batteries (typical from 11.1V to 22.2V).
The peak current of the ESC001V1 is 30A, for the B-G431B-ESC1 it is 40A.
The B-G431B-ESC1 is more compact and uses the STM32G431 microcontroller; the ESC001V1 uses the STM32F303 microcontroller.
The B-G431B-ESC1 has an embedded ST-LINK, useful for programming and debugging your application.
Both the evaluation boards can manage one motor; if you want to synchronize them, you have to use some external common signals, or use a central unit (for example the STEVAL-FCU001V1).
Here the link at user manual of the two boards for more information:
Have a nice day !
