Overview

ITEAD DUAL STEP MOTOR DRIVER SHIELD.jpg

Dual stepper motor driver shield can drive 2 stepper motors at the same time by Arduino. It can work with the power supply from 4.75V to 30V (starting from 23/07/2017, we use a new one which supports power supply from 4.75 to 15V ). High accuracy controlling can be supported by Arduino for CNC milling machine.

Installation

Dual step motor driver shield can drive 2 step motors (4 wires 2 direction) at the same time. On dual step motor driver shield, there is a setting group for micro-step resolution. They can be set by the hardware jumper, and set by pins of Arduino or other controller. And 4 settings of micro-step resolution is at the below table:
