Instructions for Use:
1. Stepper motor drive:
The ENA and ENB on the board are active high, and the level here refers to the TTL level. ENA is the enable of A1 and A2, and ENB is the enable of B1 and IB2. BJ is connected to the common end of the stepper motor.
2. Stepper motor control logic:
Among them, A, B, C, and D are the four coils of the stepping motor, and 1 means that current flows, and 0 means no current flows.
Package Included:
3 x L298N Motor Driver Board
