<br />2, can drive current: 2A (the best installation of heat sink, will be attached to the heat sink, you need to install)
<br />3, breakdown: 16 subdivision;
<br />4, the machine patch production, PCB copper 2oz (copper thickness of 70um, the general is 35um), high copper content, good heat dissipation.
<br />Core chip A4988 Introduction:
<br />
<br />This drive has the following characteristics:
<br />
<br />1, suitable for driving the following 8V ~ 35V 2A stepper motor;
<br />2, only a simple step and direction control interface;
<br />3, five different step modes: full, half, 1/4, 1/8 and 1/16;
<br />4, adjustable potentiometer can adjust the maximum current output, in order to obtain a higher step rate;
<br />5, automatic current attenuation mode detection / selection;
<br />6, overheat shutdown circuit, undervoltage lockout, cross current protection;
<br />7, ground short circuit protection and load short circuit protection;
<br /> 
<br />Suitable for:
<br />Need to drive stepper motor occasions.
<br />Is to build 3d printer, cnc, engraving machine and other essential modules.
