L298N is a high voltage, high current motor drive chip. The chip is packaged in 15 feet. The main features are: high working voltage, maximum working voltage of 46V; The output current is large, the instantaneous peak current can be triple-a, and the constant current is 2A. Rated power 25W. The high voltage large current full bridge drive with two H Bridges can be used to drive the inductive load such as dc motor and stepper motor and relay coil. Adopting standard logic level signal control; Having two enabling control terminals that allow or prohibit device work without the influence of input signals with a logical power input terminal that enables the internal logic circuit to work under low voltage; Electrical resistance can be detected and the change is feedback to the control circuit. Using the L298N chip drive motor, the chip can drive a two-phase stepping motor or four-phase step motor, and can also drive two dc motors.

instructions:

Step motor drive: ENA and ENB on the board are effective at high level, where the level refers to TTL level. ENA is the enabling end of A1 and A2, and ENB is the enabling end of B1 and IB2. BJ is connected to the common terminal of stepper motor.

The control logic of stepper motor is shown as follows, in which a, B, C and D are the four coils of stepper motor, 1 means that there is current passing through, and 0 means no current flowing through. The coil wiring diagram is shown in the figure below (taking four phase stepping motor as an example).
