GY-4988 A4988 3D Printer Driver Stepper Motor Drive Module  Description: A4988 is a complete microstepping motor driver with built-in translator for easy operation. This product is available in full, half, 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 nes, or complex interfaces to program. A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened. In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (Slow or Mixed). In mixed decay mode, the device is initially set to a fixed downtime in some fast decay, then the rest of the slow decay downtime. Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry is provided to improve the pulse-width modulation (PWM) operation power consumption. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and crossover-current protection. Special power sequencing. 

Feature:
Low RDS (ON) outputAutomatic current decay mode detection / selectionMixed with slow current decay modesSynchronous rectification for low power dissipationInternal UVLOCrossover-current protection3.3 and 5 V compatible logic supplyThermal shutdown circuitryGround fault protectionLoad short-circuit protectionStep five selectable modes: full, 1/2, 1/4, 1/8 and 1/16 Package Included: 1 X GY-4988

SUPER DELIGHTED WITH THE SERVICEI made a mistake in my initial order so I had to return the item. The very convenient Returns service meant that I could drop the item off to a nearby location. I also got the replacement item in very quick time. All in all, very good service.

21 March 2012 Top Quality Product - 66% off DIY store price Purchased door handles to match those bought a year ago downstairs. Not only are they near identical in appearance and quality but they were a third of the price.
