DC MOTOR DRIVE BOARD: 10A dual-channel motor drive board, stepping DC motor with brake H-bridge balance car drive module, DC motor high-current full-bridge drive specially designed for robot competitions. PWM MODULATION: It can work at 0%-99% PWM modulation duty cycle (note that it cannot be 100%), so that the motor can get enough driving voltage. When the motor is connected, it can not be directly given high level, and it should not be left floating. The best frequency is 400HZ Frequency: 400HZ-20KHZ! N-CHANNEL IRF3205 MOSFET: It can quickly open the MOSFET channel, improve the acceleration curvature of the motor, and also quickly brake the motor. This allows the car to start and kill the car quickly. TEST: 1. Determine the PWM signal. Before testing the drive board, please use an oscilloscope or a multimeter to determine whether the PWM you provide is accurate (set PWM to 0 when the main program is executed). 2. Do not connect the motor first, and all other power supplies are normal. Use a multimeter or oscilloscope to test the waveform between the motors. 3. Connect the motor for testing. NOTE: For customers who use for STM32 microcontrollers, please note that because these microcontrollers take a long time to initialize, it is necessary to add a 2K pull-down resistor to PWM1 and PWM2 respectively.

Features:

MOSFET driver chip comes with hardware brake function and power feedback.N-channel MOSFET IRF3205 MOSFET, use two dedicated half-bridge driver chip on the top tube using the boostrap capacitor, so that the tube has enough drive voltage of the MOSFET channel can be opened quickly, improve motor acceleration curvature, but also quickly for the motor brake. This allows the trolley can quickly start can quickly kill the car.The driver can operate at 0-99% of the duty cycle of the PWM modulation, the motor driving voltage can be obtained sufficiently.
