Features:<br>1.A4988 is a complete microstepping motor driver with built-in translator for easy operation. <br>2.It 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. <br>3.A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes. <br>4.Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and crossover-current protection. Special power sequencing.<br>5.Widely used in lab,experiment, industry, electronic DIY etc.<br><br>Descriptions:<br>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.<br><br>Specifications:<br>Color:red<br>Max current:2A<br>Modes: 1, 1/2, 1/4, 1/8, 1/16<br><br>Package Information:<br>Package size:98 x 70 x 25mm/3.86 x 2.76 x 0.98in<br>Package Weight:30g/1.06oz<br>Poly Bag Package<br><br>Package Included:<br>1 x A4988 Module
