Abstract (one paragraph) This paper presents a detailed Proteus simulation library and accompanying models for the A4988 stepper-motor driver, enabling accurate study of microstepping behavior, current regulation, and thermal effects in compact embedded systems. We introduce improved component models for the A4988’s current-limiting MOSFET bridge, internal decay modes, and microstep interpolation; validate the library against bench measurements on NEMA 17 motors for full-step, half-step, and 1/16-step modes; quantify position error, torque ripple, and heat dissipation across supply voltages (8–36 V), motor inductances (1–10 mH), and PWM frequencies (20–60 kHz); and provide a reproducible Proteus package with parameterized modules for designers and educators.

The A4988 driver is designed for bipolar stepper motors, offering built-in microstepping control for full-, half-, 1/4-, 1/8-, and 1/16-step modes. 3.3V to 5V. Motor Voltage (VMOT): 8V to 35V. a4988 proteus library download exclusive
