Keeping the jumper intact, means the 5V regulator is enabled. The module also has a 78M05 5V regulator which is enabled through a jumper. It is a dual channel H bridge motor driver which can be easily used to drive two motors. We’re going to use the L298N motor driver that can handle up to 3A at 35V. The L298N Motor driver IC is powerfully built with a big heat sink. The method we’ll use here is suitable for most hobbyist motors, that require 6V or 12V to operate. Two enable inputs are provided to enable or disable the device. The logic levels of L298N IC are compatible with. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. L298N Motor Driver IC is a 15-lead high voltage, high current Motor Driver IC with two full bridge drivers. The diagram below shows all the components consisting inside the module. The L298 is an integrated monolithic circuit in a 15-lead Multiwatt and PowerSO20 packages. Remove the jumper if the supply is greater than 12V. Introducing the L298N Motor Driver There are many ways to control a DC motor. The L298N motor driver module consists of an L298N motor driver IC, 78M05 5V regulator, 5V jumper enable, power LED, heat sink, resistors, and capacitors all combined in an integrated circuit. There is also an onboard 5V regulator – so if you’re using between 7 and 12V DC to driver the motors, the module can supply your microcontroller with 5V DC. The RPM is controlled using PWM input to ENA or ENB pins, while of rotation direction is controlled by supplying high and low signal to EN1-EN2 for the first motor or EN3-EN4 for second motor. ![]() L298N Dual Motor Controller can control both motor RPM and direction of rotation. The driver has a nice heatsink to keep the L298N cool and all driver lines are diode protected from back EMF. ![]() It is a high current dual full H-bridge driver constructed to receive standard TTL logic levels. L298N Dual Motor Controller is based on the L298N heavy-duty dual H-bridge controller, which can be used to drive two DC motors at up to 2A each, with a voltage between 5 and 35V DC. The L298N motor driver is based on the H-bridge configuration (an H-bridge is a simple circuit that lets us control a DC motor to go backward or forward.), which is useful in controlling the direction of rotation of a DC motor.
