10A Dual-channel DC Motor Drive Module PWM Speed Dimming 3-18V Low Voltage High Current

Precautions 1 The motor stops first and then reversesWhen the motor is commutation the motor needs to stop or brake The recommended time is greater than 0 5 seconds otherwise the instantaneous current of the immediate commutation may burn the module 2 Do not connect the positive and negative poles reverselyDo not connect the positive and negative poles of the power supply in reverse otherwise it will burn out Do not connect the power supply to the motor interface 3 The frequency should not be too highIn order to improve the effective work efficiency a small DC motor generally uses 400Hz The maximum PWM frequency is recommended to be within 2KHz If the frequency is too high the module will easily generate heat Function 1 Two motors can be controlled independently each of which can output current 10A peak value 15A 2 Wide power supply range 3 18V wide signal power supply range 3 18V 3 3V 5V level and power supply voltage can be used as control signals 3 The use of low voltage low resistance MOS tube can support small voltage and high current which is very suitable for model competitions Motor drive logictable INI IN2 IN3 IN4 are connected to MCU 10 or other signal sources M0T0R A M0T0R B are connected to motors MotorMotor stateIN1IN2IN3IN4MOTOR AForward rotation speed regulation 1 PWM0Reverse speed regulation 01 PWMStop00Brake11MOTOR BForward rotation speed regulation 1 PWM0Reverse speed regulation 01 PWMStop00Brake11Note 1 represents high level
