Descripción
Cada chip contiene dos puentes H completos
Viene con diodos de retroceso incorporados internamente
Usted puede hacer una prueba por su cuenta
1 entrada de PWM por conductor
Ejecute cuatro solenoides, dos motores de CC o un paso a paso bipolar o unipolar con hasta 600mA por canal utilizando el Controlador de Motor de Puente H Dual de 600 mA para CC/de pasos - L293D. Solo asegúrate de que funcionen con menos de 600mA ya que ese es el límite de este chip. Manejan un pico de 1.2A, pero eso es solo por un corto período de tiempo. Lo que más nos gusta de este controlador en particular es que viene con diodos de retroceso incorporados internamente, por lo que no tiene que preocuparse de que la patada inductiva dañe su proyecto o controlador. Estos son quizás mejor conocidos como "los controladores en el Adafruit Motorshield". Si accidentalmente dañó los controladores en un escudo, puede usar uno de estos cachorros para reemplazarlo.
exactly what i needed to drive my stepper project.. cheap and easy to use.
