CNC Shield V3 + A4988 Stepper Driver for RAMPS 1.4 Reprap 3D Printer
The expansion board can be used for engraving machine£¬ 3D printer driver extension plate£¬ a total of four stepper motor driver module slot. (Moto Sako does not contain the A4988 stepper motor driver module£¬ need to be in the store to purchase another) It can be driven by 4 road into the motor£¬ and each step electric machine only need two IO mouth. That is to say£¬ six IO mouth can be a very good management£¬ the three step stepper motor use very convenient. A4988 Stepper Motor Built-in converter; Easy to operate; Output driving performance up to 35V£¬ +/-2A; Great for dealing with complicated useless or overload applications of microprocessor. Low RDS output; Auto current decay mode check / choose; Mixture and low current decay mode; Sync rectification for lower power dissipation; Built UVLO and cross current protection; 3.3V / 5V; With over-heat off circuit and short protection; Five stepping modes: full£¬ 1/2£¬ 1/4£¬ 1/8£¬ 1/16.
