Cytron MDD3A DC Motor Driver Dual Channels 3A 4V-16V
The Cytron MDD3A is a dual-channel motor driver designed for controlling two brushed DC motors. It provides a reliable solution for driving motors with a current capacity of up to 3A continuously and 5A peak. This driver operates with input voltages ranging from 4V to 16V, making it suitable for various low-voltage applications. With its compact design and solid-state components, the MDD3A ensures smooth operation and minimal wear, as it eliminates the need for mechanical relays.
The MDD3A is controlled via PWM (Pulse Width Modulation) signals, which allows precise speed and direction control for the motors. It supports two motor channels, each with dedicated PWM inputs. The board also features motor status LEDs to indicate motor operation and test buttons for quick manual testing. It is designed for easy integration into microcontroller-based systems and offers a +5V output for powering connected components, such as microcontrollers.
The MDD3A includes key protection features such as reversed polarity protection, safeguarding the driver from damage if the battery is connected incorrectly. Additionally, it offers a high PWM frequency of up to 20 kHz, ensuring smooth motor control. The motor direction can be easily controlled by adjusting the input signal polarity, with support for both forward and backward motion. The driver’s built-in protection and user-friendly design make it an excellent choice for DIY projects and automation systems.
