Are you looking for a module that can control motors using a 5V signal? Let’s take a look at the L298N Module.
It solve the issues that the motor current is much higher than the supply current of the microcontroller and the issue that the supply voltage is insufficient. And it also with the function of galvanic isolation and of providing 5V power supply to the external environment separately when powered by low voltage (<24V).
Through rational design, not only can the microcontroller be used to control larger voltage and current output to the motor, but also can be used to control the rotation speed and direction of the motor. It can also protect the microcontroller from being affected when the motor is short circuited.

Pin Definition
12V Input is the power input interface, which is used for an external power supply to the L298N.
5V Output is the power output interface, which can be used to supply power to the Arduino microcontroller.
The GND interface is a ground level interface, which can be used to connect to the negative terminal (GND) of the power supply or the GND of the Arduino.
IN(1,2,3,4) is the input port of signal, which can be used to connect to the signal output port of Arduino, raspberry pi and other microcontrollers to control the high and low levels of the output, thereby controlling the forward and reverse rotation of the motor.
OUT A and OUT B are output ports, which can be used to connect to the motor. Enable is the enable port, high level is valid. Only when 5V voltage is connected, the output port work.
Usage Instruction:
When the power input (marked as+12V or VCC on the board) is 7V-12V, the integrated circuit is powered by the 78M05 integrated circuit, and at this time, the +5V in the port is the power output of the module.
Notes: not to connect other power supply at this time, only power supply to other equipment, such as Arduino microcontroller, etc.
When the driving voltage is higher than 12v (Although the manual of 78M05 integrated circuit states that it can support up to 35V, but based on experience, the max. voltage for conservative applications of 78M05 up to 24V has already reached the limit, and higher voltage may lead to overheating and burnout! So normally when the voltage exceeds 12V, a power supply from logic judgment is provided to the L298N integrated circuit separately. At this time, you need to pull up the input jumper cap of 78M05 and connect a 5V power supply from +5V separately).
Product Features
1.Support dual power supply, can provide larger current output.
2.Can directly drive bipolar motors and stepper motor.
3.With protection functions for power over-voltage and over-current.
4.Can control two DC motors at the same time or one stepper motor.
5.Support PWM speed regulation, to achieve precise control of the motor.
6.Small in size, simple in operation, easy to integrate into various electronic devices.
7.Compared to other motor drive modules, L298N is rich in function, lower in prices and cost-effective.
Notes
1.The power supply must not be reversed! The power supply must not be reversed! The power supply must not be reversed!
2.If a separate external power supply is required for the 5V logic power supply of L298N, please connect the GND of the microcontroller, the GND of the L298N and the GND or negative pole of the power supply together, to ensure the stability of the signal.
3.The rated current of the power supply must be two times higher than the rated current of the module, in order to prevent the power supply from being overloaded with excessive current during motor startup.
4.Before reversing the motor, please stop it for 100ms and then startup. Otherwise the induced electromotive force generated by the motor operation may breakdown the module.
5.If used in a humid environment, please check whether the circuit is rust and short circuit in advance. And if conditions permit, please used in a good heat dissipation environment.
6.The L298N on-board 5V enable interface is not used normally, so do not pull up its jumper cap.
