Cytron MDD3A - dual-channel 16V / 3A motor controller

Product description: Cytron MDD3A - dual channel motor controller DC 16V/3A

The Cytron MDD3A motor controller has the ability to control 2 DC motors or 1 stepper motor. Continuous current per channel is 3 A (momentary 5 A). Supply voltage is from 4V to 16 V.The controller works with logical voltage of 1.8 V, 3.3 V, 5 V and 12 V (PWM)so it can be controlled by any microcontrollersuchas Arduino or Raspberry.Forproper operation the module does not require an additional Arduino type controller,the controllercan be controlled by means of buttons on theboard.

The controller has built-in buttons for quick system testing.

Product compatible with Arduino

Outputs of Cytron MDD3A - dual channel DC 16V/3A motor controller

The controller is equipped with a 6-pin 2.54 mm input from which it receives information from the microcontroller about the direction and speed of rotation of the motors and 6 screw connectors to which the motors and power supply are connected.Cytron MDD3Acan be controlled by inputsPWM. The logic voltage is 1.8 V, 3.3 V, 5 V or 12 V, is compatible with most controllers, such asArduino,Raspberry Pi...PLC.
