Features: brand new and high qualityMotor driver board 12-36V for DC power input , VCC positive power supply,GND power supply is negative.Pulse speed signal: high and low output . IC can not understand the information with the customer requestThis board has many functions such as stall for protection, enable control, over-current for protection, steering control and speed control signal.This driver board has many advantages including low consumption, high reliability and efficiency.Electrical wiring: three-wire brushless for DC motor, corresponding to MA/U, MB/V, MC/for WTip: If you use a heat sink smaller than 60W and no additional heat sink, you must add a heat sink above 60W. If the driving efficiency of the heat sink is not reduced, excessive temperature will cause sexual damage!Specifications: Operating voltage: for DC 12V-36VOperating Current:
