MP6550 DC motor controller module. It allows controlling the movement of a DC motor with a voltage from 1.8 to 22 V and a current of up to 1.7 A (continuous current). The interface requires two PWM control lines. The controller has built-in protection against reverse polarity, over voltage, overload and overheating. The logic part can be supplied with a voltage from 1.8 to 5 V, so the module can work with 3.3 V and 5 V.
