It has many advantages including adjustable current limiting, over temperature and over current protection. It has five different stepping resolution and has a wide operating voltage range from 8 volt to 35 volts and can deliver current upto 1 Amp per phase.<\/p>\n<p>The A4988 is a complete micro-stepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with an output drive capacity of up to 35 V and \u00b12 A. The A4988 Motor Driver includes a fixed off-time current regulator which has the ability to operate in Slow or Mixed decay modes.<\/p>\n<p>The translator is the key to the easy implementation of the A4988. Simply inputting one pulse on the STEP input drives the motor one micro-step. There are no phase sequence tables, high frequency control lines,or complex interface sto program. The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened. During stepping operation, the chopping control in the A4988 automatically selects the current decay mode, Slow or Mixed.<\/p>\n<p>In Mixed decay mode, the device is set initially to a fast decay for a proportion of the fixed off-time, then to a slow decay for the remainder of the off-time. Mixed decay current control results in reduced audible motor noise, increased step accuracy, and reduced power dissipation.<\/p>\n<p>Features:-<\/p>\n<ul>\n<li>Simple step and direction control interface<\/li>\n<li>Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step<\/li>\n<li>Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor\u2019s rated voltage to achieve higher step rates<\/li>\n<li>Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)<\/li>\n<li>Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection<\/li>\n<li>Short-to-ground and shorted-load protection<\/li>\n<li>4-layer, 2 oz copper PCB for improved heat dissipation<\/li>\n<li>Exposed solderable ground pad below the driver IC on the bottom of the PCB<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>Specifications:-<\/p>\n<ul>\n<li>Minimum operating voltage: 8V<\/li>\n<li>Maximum operating voltage: 35V<\/li>\n<li>Continuous current per phase: 1 Amp<\/li>\n<li>Maximum current per phase: 2 Amp<\/li>\n<li>Minimum logic voltage: 3V<\/li>\n<li>Maximum logic voltage: 5.5V<\/li>\n<li>Microstep resolutions: Full, 1\/2, 1\/4, 1\/8, and 1\/16<\/li>\n<li>Reverse voltage protection?: No<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Description:- A4988 Module is a \u00a0Smaller and Cheapest breakout board for Allegro&#8217;s A4988 Stepper Motor Driver.
