A4988 Stepper Motor Driver Proteus Library Download [verified] -

| Proteus Pin Label | Actual A4988 Pin | Function | |------------------|------------------|-----------| | EN | Enable | Active low. Pull low to enable outputs. | | MS1 | Microstep select 1 | Sets microstepping resolution (with MS2, MS3). | | MS2 | Microstep select 2 | | | MS3 | Microstep select 3 | | | RST | Reset | Active low. Resets the driver. Tied to VCC if not used. | | SLP | Sleep | Active low. Pull high for normal operation. | | STP | Step | Each pulse advances the motor one step/microstep. | | DIR | Direction | High = clockwise, Low = counterclockwise. | | VDD | Logic supply | 3.3V to 5V (connect to microcontroller VCC). | | GND | Logic ground | Common ground with microcontroller. | | VMOT | Motor supply | 8V to 35V (simulation may use 12V DC). | | GND (power) | Motor ground | Return path for motor current. | | 1A, 1B | Coil 1 | Connect to stepper motor coil A. | | 2A, 2B | Coil 2 | Connect to stepper motor coil B. |
