Product Description5pcs A4988 Stepstick Stepper Motor Driver Module with Heat Sink for 3D Printer Reprap Suitable for Mendel Huxley Arduino

• Simple step and direction control interface,Take anti-static measures before you use the A4988 modules in case of short-circuit
• Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step. Output drive capacity of up to 35 V and ± 1.2 A
• Adjustable current control lets you set the maximum current output with a potentiometer
• Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
• Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection

Parameters:
Size: 1.5mmX2mm (for RAMPS, ultimaker or other compatible boards);
The drive current: 2A (best to install the heat sink)
Segments: 1,1 / 2,1 / 4,1 / 8,1 / 16
Manufacturing process: higher SMT placement machine manufacturing, non-manual welding, yield, more stable performance.

Applications:
Stepper motors /3D printer/CNC/engraving machines/Supported 3d printers like Prusa Mendel, ultimaker, printbot, makerbot and so on.You can refer to the Arduino code at the back of the module.
