Product Description

A4988 Stepper Motor Driver Module with Heatsink

The A4988 driver Stepper Motor Driver, Good quality is a complete micro-stepping motor driver with built-in converter, easy to operate. The products can be in full, half, 1/4, 1/8 and 1/16 step mode of operation bipolar stepper motor, output drive performance up to 35 V and ± 2 A. a4988 driver Stepper Motor Driver includes a fixed off-time current regulator, the regulator can be in slow or mixed decay mode. The converter is the key to the easy implementation of the A4988. As long as the input of a pulse in the “step” in the input can be driven motor, micro-step.

There are no phase sequence tables, high-frequency control interface programming or complex. The application of A4988 interface is very suitable for a complex microprocessor is not available or overload. In the stepping operation, the chopping control in the A4988 automatically selects the current decay mode (slow or mixed). The mix decay current control scheme can reduce the audible motor noise, increased step accuracy, and reduced power consumption.
