More info


Cytron MD20A is a motor controller that allows you to control the speed and direction of the DC motor with a voltage in the range of 6-30 V. Based on MOSFET transistors so it can control current up to 20 A without additional cooling. The module can be controlled via PWM and DIR inputs. Thanks to the input logic voltage range from 1.8 V to 12 V, it is compatible with a wide range of controllers.

Embedded test buttons and engine output LEDs allow functional testing of the motor controller in a quick and convenient way without connecting the controller.

Power input does not have reverse-voltage protection. Connecting the battery in reverse polarity will damage the motor driver instantaneously.
