Pins:-
 
Out 1: Motor A lead out
Out 2: Motor A lead out
Out 3: Motor B lead out
Out 4: Mo (Can actually be from 5v-35v, just marked as 12v)
GND: Ground
5v: 5v input (unnecessary if your power source is 7v-35v, if the power source is 7v-35v then it can act as a 5v out)
EnA: Enables PWM signal for Motor A (Please see the “Arduino Sketch Considerations” section)
In1: Enable Motor A
In2: Enable Motor A
In3: Enable Motor B
In4: Enable Motor B
EnB: Enables PWM signal for Motor B 
 
Applications:-
H-bridges are typically used in controlling motors speed and direction but can be used for other projects such as driving the brightness of certain lighting projects such as high powered LED arrays.
