Stepper Motor Driver A4988
PRODUCT ID: MOT-MOT-004
A4988 is a complete microstepping motor driver with built-in translator for easy operation. This product is available in full, 1/2, 1/4, 1/8 and 1/16 step modes operate bipolar stepper motors, output drive capacity of up to 35 V and 2 A.
A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes. A4988 converter is the key to the easy implementation. As long as the "step" input inputting one pulse drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program. A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened.
