28BYJ-48 Stepper Motor Module with A4988 Driver

The 28BYJ-48 stepper motor module is a compact all-in-one solution for precise motion control in robotics and automation projects. It combines a proven 28BYJ-48 geared stepper motor with a powerful A4988 stepper motor driver on a single board. This integrated architecture significantly reduces wiring effort and enables quick and clean motor control setups. The motor operates at 5 V operating voltage and achieves high torque of up to 0.9 kgf·cm thanks to the 1:64 reduction gear, while providing fine positioning. Control is via just four pins (STEP, DIR, 5V, and GND), allowing the module to be easily connected to microcontrollers such as Arduino, Raspberry Pi, or ESP32. In half-step mode, 4096 steps per revolution are available, and microstepping allows even finer movement sequences. Four fixed integrated M3 nuts provide stable mounting, while the included accessories enable immediate project start.
