In addition the regulator only works with voltages up to 12V in Vin, above this value we will have to remove the jumper and feed the logical part of the module from another source.

Watch out! If we introduce current by logic V with the regulation jumper set, we could damage the module.

If we remove the jumper we will deactivate the regulator, we will need to feed the logical part of the module, so we will have to put a voltage of 5V through the V logic connection for the module to work.

If the regulator jumper is closed we will activate the voltage regulator of the L298N, and in V logic we will have a 5V output, which we can use for what we want, for example to power an Arduino board.

It is a module that is widely used in robotics projects, for its ease of use and its low price. Of course, this regulator only works if we feed the module with a maximum voltage of 12V.

In addition, the L298N includes a voltage regulator that allows us to obtain a voltage of 5V from the module, perfect for powering our Arduino. When it is time to feed it, it is necessary to take into account that the electronics of the module consume about 3V, so the motors receive 3V less than the voltage with which we feed the module. The voltage range in which this module works ranges from 3V to 35V, and an intensity of up to 2A. We have talked about them before, but basically an H-bridge is a component formed by 4 transistors that allows us to reverse the direction of the current, and in this way we can reverse the direction of rotation of the motor.

The L298N H-bridge driver board module allows us to control the speed and direction of two DC motors or a stepper motor in a very simple way, thanks to the 2 H-bridge it is mounted on.
