Feature

●HEATSINK EQUIPPED The upgraded product comes with heatsink to improve reliability and current detection to realize a perfect PID closed loop design.
●SPEED SWITCH This board has a high speed switch. General coreless motors require 60kHz PWM frequency and this board is equipped with a 200kHz switch.
●Widely Used This motor controller is suitable for all kinds of toy car engines, semiconductor cooling control, DC motors, electromagnetic deflection coil control.
●Can Stand High Current This motor control board can withstand high current overloads and has a braking function that quickly stops the motor.
●Wide input voltage: input voltage range of this board is 3V to 15V, if you use a power source less than 12V, this board is very useful. It can still work, even the voltage of a 12V battery is as low as 3V.
