5PCS A4988 Driver Module StepStick Stepper Motor for CNC Reprap 3D Printer

Description

This item is stocked & dispatched from California US.
Package includes:
5x A4988
5x Heat sink
Key Features:
This product can operate bipolar stepper motors in full, half, 1/4, 1/8 and 1/16 step modes
Output drive performance up to 35 V and 2A
The A4988 includes a fixed off-time current regulator that operates in slow or mixed decay modes
The converter is the key to the easy implementation of the A4988. Just enter a pulse in the "step" input to drive the motor to generate microsteps
No need for phase sequence table, high frequency control line or complicated interface programming
The A4988 interface is ideal for applications where complex microprocessors are unavailable or overloaded.
Electrical Specifications:
Suitable for driving step motors below 8V ~ 35V 2A;
Simple step and direction control interface;
Five different step modes: full, half, 1/4, 1/8 and 1/16;
Adjustable potentiometer can adjust the maximum current output, so as to obtain a higher step rate;
Automatic current attenuation mode detection / selection;
Over-temperature shutdown circuit, under-voltage lockout, cross-current protection;
Short-to-ground protection and short-to-load protection
3.3V and 5V compatible logic current
Driving current algorithm: I = V * 0.8, the potentiometer has three pins. Use a multimeter to test the voltage between the pin facing 4988 and GND. The current can be adjusted by the potentiometer. Clockwise is to increase the current.Counterclockwise is to increase the current.
