Check the listing for details. 30A 3-55V Dual-Channel DC High-Power H-Bridge Motor Driver Board Module. Condition: New. Listed at 129.13 USD. Title： 30A 3-55V Dual-Channel DC High-Power H-Bridge Motor Driver Board Module Features: 1. PWM supports 0--100%, supports high-level full-speed operation.2. Less resources are occupied, and only one PWM control is required for each channel.3. The motor end supports a wide voltage range of 3V to 53V, under-voltage protection, and power supply transient interference suppression.4. Support two motors to be controlled separately. The maximum rated current of each channel is 30A, which can be automatically adjusted according to the load in the range of 0--30A.5. The peak current of each channel reaches 100A, which supports frequent startup, forward and reverse rotation, and acceleration.6. The control terminal and the motor terminal are effectively isolated, and the isolated power supply is used, and the high current operation does not affect the single-chip microcomputer.7. Support 3-5.5V control signal, this range supports most microcontrollers.8. It can be separated from the MCU and directly controlled by an external switch Specification: Rated voltage: 3v-55vRated current: 30APeak current: 100APWM frequency range 400HZ--50KHZBest working frequency 5KHZ-24KHZScope of application: Control circuit of various DC motorsSize: length 100mm, width 60mm Control signal: EN1 and EN2 are the enable terminals of the two channels respectively, and the low level is active; DIR1 and DIR2 are the control directions of the two channels respectively, PWM1 and PWM2 are respectively the control speed of the two channels, PWM is 0 to 100%, the larger the speed, the faster Motor end connection: POWER is connected to the positive pole of the power supply, and GND is connected to the negative pole of the power supply. The two motors are connected to MOTOR1 and MOTOR2 respectively Packing: 1*H-Bridge Motor Driver Board Module
