The module, with the L298N as controller, is a double H-bridge motor driver with little heat production and interference. The module can even handle a peak voltage of 46v and a peak current of 3A.
This module can control up to 2A with a power of 25w. With this a 2-phase stepper motor, a 4-phase stepper motor or two DC motors can be driven.
The built-in 78M05 chip is powered by the driver voltage, so when the driver voltage rises above 12V, an external 5V power supply must be connected.
