diymore Dual Channel DC Motor Driver Shield Expansion Board L298NH Drive Module Replace L298P for Arduino UNO R3 MEGA2560

It lets you drive two DC motors with your Arduino board controlling the speed and direction of each one independently. You can also measure the motor current absorption of each motor among other features. You can find in the Getting Started section all the information you need to configure your board use the Arduino Software (IDE) and start tinker with coding and electronics. The adapter can be connected by plugging a 2.1mm center-positive plug into the Arduino's board power jack on which the motor shield is mounted or by connecting the wires that lead the power supply to the Vin and GND screw terminals. Manufactured by diymore. This shield has two separate channels called A and B that each use 4 of the Arduino pins to drive or sense the motor. In total there are 8 pins in use on this shield. You can use each channel separately to drive two DC motors or combine them to drive one bipolar stepper motor. If you don't need the Brake and the Current Sensing and you also need more pins for your application you can disable this features by cutting the respective jumpers on the back side of the shield. Free running stop and brake function. The Motor Shield is based on the L298NH which is a dual full-bridge driver designed to drive inductive loads such as relays solenoids DC and stepping motors.
