9-24V 2/4 Channel High Power DC Motor Drive Kit PWM Adjust Speed with Arduino Development Board Smart Car Controller
DC motor drives:
-The two-way DC motor drive module is only 5cm × 5cm × 1.25cm, which is equivalent to four one-yuan coins. This module has two motor channels, which can drive two motors to rotate at the same time, and each channel is equipped with an indicator light to prompt the motor to turn. Blue means forward and red means reverse. The support voltage range is 6.5-28V, each channel can continuously output 12A current, and can drive 290W electric power DC motor. The instantaneous peak current can reach 70A and can last for about 100ms. At the same time, the timing of the device in the driver is highly optimized, allowing the minimum pulse width of the PWM input to be as low as 2us, which fully guarantees the dynamic adjustment range of the PWM and improves the control quality of the motor.
-The module has built-in over-voltage, under-voltage, and over-temperature protection circuits. As long as the voltage is too high, the voltage is insufficient, and the on-board temperature is too high, the protection measures will be triggered immediately. The protection status is output by the indicator in real time. When it is always on, it indicates normal operation. ; Fast flashing indicates over-voltage of the power supply; Slow flashing indicates under-voltage of the power supply; Double-flashing indicates overheating of the driver; All three phenomena will turn off the output, effectively reducing the possibility of the driver being damaged under abnormal working conditions.
-The control input terminal is a 2.54mm pitch 2x5 double-row pin, which can be used directly on breadboards and prototype boards. It is very convenient to use and meets various DIY requirements.
-With Arduino source code, motor control can be easily realized, motor speed can be controlled, forward and reverse and stop, can be used in a variety of occasions such as automated robots, mechatronics, equipment manufacturing, scientific research and production, electronic competitions. In the maker era, we can bring you more!
