Copy the extracted .LIB and .IDX files and paste them into the Proteus library folder.

: Features thermal shutdown and crossover-current protection. Wiring Tips for Simulation

Connect to Ground (GND) or a microcontroller pin. Active low, meaning it must be pulled low to turn on the driver FET outputs.

Before jumping into the simulation environment, it is essential to understand the core architecture of the A4988. The A4988 is a complete microstepping motor driver with a built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with an output drive capacity of up to 35 V and ±2 A.

: Place an Arduino Uno (requires an Arduino Proteus library) or any MCU like a PIC or ATmega.

Test your code (Arduino, PIC, STM32) without risking physical hardware.

: Supports higher current (up to 2.2A) and 1/32 microstepping.
