3 Pcs Skydio A4988 Stepper Driver 3d Printer Driver Control Board 3d Printer Mo

Description A4988 Is a complete microstepping motor driver, With built-in converter, Easy to operate. The product is available in the whole, half, 1/4.1/8 and 1/16. A fixed off time current regulator, The regulator can work in slow or mixed attenuation mode. The converter is A4988 Key to easy implementation. As long as it is in" Stepping" Input a pulse in the input, Microstep can drive motor. No need to carry out phase sequence table. High frequency control line or complex interface programming. A4988 The interface is very suitable for complex microprocessors unavailable or overloaded applications. Feature - Color: As shown- Material: PCB- Size: 2 x 1 0.5cm- Simple step and direction control interface- Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection- Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)- Short-to-ground and shorted-load protection- Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor&
39;s rated voltage to achieve higher step rates- Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-stepPacking list: 3 Pcs x StepStick Stepper Driver
