Using ST’s L298N as the main driver chip, it has the characteristics of strong driving capability, 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 operating current of 2A
Rated power 25W
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; Having two enable control terminals that allow or prohibit device operation without being affected by input signals. There is also a logic power input terminal that allows the internal logic circuit to operate at low voltage
An external detection resistor can be connected to provide feedback on the change to the control circuit
It can drive one two-phase stepper motor or four phase stepper motor, or drive two DC motors.
The module can be powered by the built-in 78M05 through the driver power supply, but to avoid damage to the voltage regulator chip, when using an external 5V logic power supply,
The module uses large capacity filtering capacitors and freewheeling protection diodes to improve reliability.
