I am trying to control a DC Motor with a DRV8833. To be precise, I have this module from MJKDZ (which, I believe, is not the original one from TI).

Every output pin has 0V (including “ULT”, which may indicate a fault condition). All grounds (ESP32, battery, etc) are connected.

Do you think I may have overheated it while soldering the pin sockets (I learned soldering when I was a kid from my father probably like many of you, but I didn’t do it for a while and now I am terrible at it)? Or could it be an over-current issue?

So, just to be sure that the issue is really on this particular module, could I try connecting an even simpler circuit like this (basically excluding things related to ESP32):

and expect the potential difference between OUT1 and OUT2 to be 5 V ?motor-controllershareedit  follow  flagedited Nov 10 at 10:42tlfong011,26911 gold badge55 silver badges99 bronze badgesasked Nov 9 at 20:19Onur Celebi4955 bronze badges New contributor

@brhans you are right, it was the EEP pin. On this image I thought the jumper not been soldered, letting EEP unconnected would enable the device, but it was the opposite.
