Description

Note:The Color Of A4988 Will Be Shipped In Random(green or red)CNC Shield Board:Each road stepper motors only need two IO ports.This expansion board as a driver expansion board, can be used for engraving machines, 3D printers.It is a total of four slots, can drive four A4988 stepper motor. Each road stepper motors only need two IO ports. In other words, six IO ports can be well managed three stepper motors. Very convenient to use.Stepper motor wiring as follows: 2A, 2B is a group (red, green), 1A, 1B is a group (blue, yellow), if want to change direction, can be change the position of one group , for example 2A, 2B mutually exchanged.PWM Spindle and direction pins. 4-Axis support. Runs on 12-36V DC.A4988 Driver Module:Simple step and direction control interface.Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step. Output drive capacity of up to 35 V and ± 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.Package List:1x CNC Board4x A4988 Driver4x Heat Sink1x Screwdriver
