B-g431b-esc1 vs steval-esc001v1

[Hannibal]

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:

• STEVAL-ESC001V1
• B-G431B-ESC1

Have a nice day !
