I have some concerns with the L296N module.
Let's consider the below module notation.
I understand what all the connections do except the pair (7 and above) and (12 and above). Let's consider only the pair 7 and above(7b). To what should be 7 and 7b connected? To two different GPIO or to GPIO and GND?
Why do they need 2 pins for the motor direction?Souldn't be only one enough since there are only two directions?(HIGH-HIGH and LOW-LOW encodings are not used).
