This module uses L298N as the main driver chip, the peak operating voltage can reach 46V; the output current is large, the instantaneous peak current can reach 3A, the continuous operating current can be 2A, and the rated power is 25W. Inductive loads such as high-stepper motors and relay coils containing two H-bridges are controlled by standard logic level signals. It has two enable control terminals, which allow or prohibit the operation of the device without being affected by the input signal. There is a logic power input terminal so that the internal logic circuit part works at a low level; an external detection resistor can be connected to feed back the change to the control circuit. The chip can drive a two-phase stepper motor or a four-phase stepper motor, or two DC motors. The module can use the built-in 78MO5 to draw power from the driving power supply section. In order to avoid damage to the voltage stabilizing chip of the module, when using a driving voltage greater than 12V, please use an external 5V logic power supply. The module uses filter capacitors and freewheeling protection diodes to improve reliability.

        When your driving voltage is 7V-12V, you can enable the onboard 5V logic power supply. After using the onboard 5V power supply, the +5v power supply in the interface does not require input voltage, but the 5V voltage can be drawn out for external use. (This is a normal use method!) 2. When the driving voltage is higher than 12V and less than or equal to 24V (the chip company's documentation states that it supports up to 35V, in actual applications, it is generally good to support the conservative application voltage of L29N up to 24V!), for example, to drive a motor with a constant voltage of 18V. First, you must remove the onboard 5V output enable jumper cap. Then connect the 5V5V enable, that is, a control signal with a level of 5V, to the outside of the 5V output port. When this signal input is valid and the power supply in the motor drive module is normal, the motor drive module outputs current. Otherwise, even if the power supply is normal, there will be no current or voltage on the motor to supply power to the internal logic circuit of L298N. (This is the normal use of high-voltage drives!)
