Description:
The A4988 Stepper Motor Driver Module is a compact and efficient solution for controlling bipolar stepper motors in various applications, including 3D printers, CNC machines, and robotics. It features the Allegro A4988 microstepping driver, capable of operating in full, half, quarter, eighth, and sixteenth-step modes, providing precise control over motor movement. The module supports a wide input voltage range from 8V to 35V and can deliver up to 2A per coil with adequate cooling, making it suitable for a variety of stepper motors, such as the NEMA 17.
Designed for ease of use, the A4988 module requires only two control pins—STEP and DIRECTION—to manage motor operation, simplifying integration with microcontroller platforms like Arduino and Raspberry Pi. It includes adjustable current limiting, over-temperature shutdown, and cross-current protection features to ensure reliable and safe operation. The module’s compact size and straightforward interface make it an ideal choice for projects requiring precise and efficient stepper motor control.
