My mistake. In the first instance I measured voltage without a motor connected, over 2A/2B and 1A/1B, and nothing registered.
I didn't apply voltage to VMOT/GND though; Will I still registers something over 2A/2B and 1A/1B?
This is what I was after in the previous post, thanks. The same question applies here though, if I hook up a motor, won't I have to add power on VMOT/GND to get it to move?
