MX1508 DC Motor Driver Module PWM Speed Dual H-Bridge Stepper Motor (L298N mini) Soldered:Without Soldered Pin 5 fixture hole 4pcsSIM900A serialDetails: Dual H bridge motor driver, can drive two DC motors or a 4 wire two phase stepper motor. The module supply voltage 2V 10V. Signal input voltage 1. 8 7V. Single Operating current 1. 5A, peak current up to 2. 5A, low standby current (less than 0. 1uA). Built in common conduction circuit, when the input pin is left floating, the motor does not malfunction. Built in thermal protection circuit with hysteresis effects (TSD), without worrying about
