Controlling DC motors through L298N module and MicroPython Motor A having voltage between 5-35V, will be connected through these two terminals. ENB This pin controls the speed of the motor B by enabling the PWM signal. They control the spinning direction for that particular motor. IN3 & IN4 These are the input pins for motor B.
IN1 & IN2 These are the input pins for motor A. ENA This pin controls the speed of the motor A by enabling the PWM signal. If jumper is intact, then it acts as an output pin. Will be used only if the 5V enable jumper is not intact. 5V This pin supplies the power (5V) for the internal circuit (L298N IC). It is imprinted with +12V on board but can be powered between 6-12V. Pin Name Description VCC This is the pin which supplies power to the motor. Let us now look at the pinout of the module. The table shows some specifications of the L298N motor driver module: Driver Model L298N Driver Chip Double H-bridge L298N Maximum Power 25W Maximum Motor Supply Voltage 46V Maximum Motor Supply Current 2A Driver Voltage 5-35V Driver Current 2A Size 43x43x26mm L298N Module Specifications PinOut Note: If the jumper is connected, do not supply power to both the motor power supply input and the 5V power supply input. If the power supply is more than 12V, make sure the jumper is not intact and supply 5V power through the pin separately. The 5V pin in this case acts as an output to power the microcontroller. If the motor power supply is less than 12V then we will power the module through the voltage regulator.
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. The L298N Motor driver IC is powerfully built with a big heat sink. The diagram below shows all the components consisting inside the module. The L298N motor driver module consists of a L298N motor driver IC ,78M05 5V regulator, 5V jumper enable, power LED, heat sink, resistors and capacitors all combined in an integrated circuit. This module is mainly used in robotics and in controlling dc and stepping motors. Thus, it is perfect for two wheeled robots. It is widely used in controlling robots as we can connect up to four motors at once but if we want to control the speed and direction as well than it allows two motors to be connected. For this project, we will be using L298N motor driver module as it very easy and relatively inexpensive as well.
