The Rhino Dual Driver 20A enables bidirectional control of two high-power brushed DC motors from 6V to 0V. With full discrete NMOS H-
Bridge design, this motor driver is able to support 20Amp continuously for each motor without any heat-sink
The onboard test buttons and motors output LEDs allow functional test of the motor driver in a quick and convenient way without hooking up
the host controller. This motor driver can be controlled with PWM and DIR inputs.
it’s compatible with wide variety of host controller (e.g. Arduino, Raspberry Pi, PLC).
The advantage of this drive is that all inputs are electrically and optically isolated.
Various protection features are also incorporated in each channel of the Rhino 20A. Over-current protection prevents the motor driver from
damage when the motor stalls or an over-sized motor is hooked up. When the motor is trying to draw current more than what the motor
driver can support, the motor current will be limited at the maximum threshold.
Assisted by temperature protection, the maximum current limiting threshold is determined by the board temperature. The higher the board
temperature, the lower the current limiting threshold. This way, Rhino Dual Driver 20A able to deliver its full potential depending on the
actual condition without damaging the MOSFETs.
Note: Power input does not have reverse-voltage protection. Connecting the battery in reverse polarity will damage the motor driver
instantaneously.
Note : Peak current is limited by the over-current protection circuit. Actual current limit is depending on board
temperature. Value shown is at room temperature (25 - 0 degree Celsius).

As depicted in fig 4 , there is a provision to connect two motors to the driver, with a power supply positioned in between.
To initiate a test run of the motors, you can conveniently utilize the push buttons integrated into the driver, specifically
M1A_ W and M1B_ W for motor 1, and M2A_ W and M2B_ W for motor 2.
It is important to note that the direction of each motor is determined by its individual connection.
Reversing the motor's connection will result in a reversal of its direction
of rotation. Reversing the connection of motor will reverse its direction.
The motors can be easily controlled using any microcontroller equipped with 5V pins. By providing PWM signals to the PWM pins
of the drive (PWM1 and PWM2), the motor speed can be adjusted accordingly.
To change the direction of the motors, a signal from any digital 5V pin can be directed to the corresponding direction pins
(DIR1 and DIR2). Furthermore, to stop the motor motion, a 5V signal from any digital pin can be applied to the sleep pins of the
drive ( LEEP1 and LEEP2). For a visual representation of these connections, please refer to fig 5 on the subsequent page.
If you intend to control the motor's speed using a potentiometer, you will need to employ a microcontroller such as Arduino.
This microcontroller can receive input from the potentiometer and subsequently provide output to the PWM pins of the drive.
For a visual reference regarding this setup, please refer to fig 6 on page 13.
