SPECIFICATIONS

Parameters:
Using ST company's L298N as the main driver chip, it has the characteristics of strong driving ability, low heat generation, and strong anti-interference ability
The output current is large, with an instantaneous peak current of up to 3A and a continuous working current of 2A
Rated power 25W
A high voltage and high current full bridge driver with two H-bridges, which can be used to drive inductive loads such as DC motors, stepper motors, relay coils, etc
Using standard logic level signal control; There are two enabling control terminals that allow or prohibit the operation of the device without being affected by the input signal. There is a logic power input terminal that allows the internal logic circuit to operate at low voltage
It is possible to externally detect the resistance and feedback the change to the control circuit
It can drive one two-phase stepper motor or four phase stepper motor, as well as two DC motors.
The module can use the built-in 78M05 to power up and work through the driver power supply. However, to avoid damage to the voltage regulator chip, when using an external 5V logic power supply,
The module uses a large capacity filter capacitor and a continuous current protection diode, which can improve reliability.

Introduction (III) Instructions for Use
1.5V voltage connection method
When a 5V motor needs to be driven, the+12V and+5V terminals at the input end are short circuited and the input voltage is 5V
2.12V voltage connection method
When the input driving voltage of the+12V terminal is 7-12V, the+5V terminal should not be connected to the input voltage and can be used as a 5V output voltage for external use.
3.When the driving voltage at the input end is higher than 12V but less than or equal to 24V, the jumper cap that enables 5V output on the board must be removed, and then a 5V voltage must be connected externally to the 5V output port to supply power to the internal logic circuit of L298N.
