10Amp 7V-35V SmartDrive DC Motor Driver (2 Channels)

This MDDS10 is our advanced dual channel brush motor driver, designed for a wide range of applications including combat and sumo robots. With an input voltage range of 7-35VDC, this driver is capable of single power operation and features dual channels, allowing for bidirectional, independent, or mixed drive of two brush motors.

This driver offers multiple operating modes including RC (RC servo signal), Analog, PWM, and simplified and packetized UART. It also supports Sign-magnitude and Locked antiphase in PWM mode.

There are two manual/test buttons and two output indicator LEDs for each channel, as well as power, error indicator, and RUN status LEDs. The error LED will indicate various issues such as error input, under voltage, over voltage, over temperature, and shut down. A reset button is also provided for easy operation mode changes.

This driver features full solid state MOSFET for better efficiency and eliminates the need for external flyback diodes. Additionally, regenerative braking and temperature feedback are included to reduce output current and prevent overheating of the MOSFET.

This driver can support up to 10A continuous current at room temperature (25ºC) and 30A peak for 10 seconds, but note that output will be reduced with temperature raises. The switching frequency is 16KHz for quiet operation, and it has an on-board switching voltage regulator for higher power efficiency.

This driver is suitable for use with single power window motors at 24V, as it has been tested without smoke coming out. Please note that there is NO polarity protection, so double-check the power input connection. Dimensions of the board are 66.8mm x 101.09mm.

Features:

• Input Voltage (Motor): 7 - 35VDC
