Detail

A4988 Characteristics: 
1. Suitable for driving stepper motors below 8V ~ 35V 2A; 
2. Very simple step direction control interface; 
3. Five different stepping modes: full, half, 1/4, 1/8 and 1/16; 
4. Adjustable potentiometer can adjust the maximum current output, can get better step rate; 
5. Automatic current decay mode detection / selection; 
6. High heat will result circuit cut, undervoltage lockout, crossover current protection; 
7. Ground short-circuit protection and load short-circuit 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.
