Keyes EB0017 Two-Channel Stepper Motor Drive Shield Expansion Board

The dual-stepper motor drive shield features a fluent easydriver solution that can drive two stepper motors simultaneously. Attach a 4.75V ~ 30V power supply to have your robot perform new and complex tasks. Control the stepper motor via the simple IO port and PWM control.

Arduino can provide high-precision control for CNC milling machines. The stepper motor driver chip is the same as EasyDriver which means you can use it as two EasyDriver modules on the board. 

Customise the expansion board by adding buttons, LED displays and relay switch functions. The stepper motor drive comes with two types of wiring, including connection terminals and pins, which can be used for different programs. Thie4-wire 2-phase stepper motor drive shield is designed specifically for Arduino.

Features:
• Convenient for some two-axis CNC projects.
• Compatible with 3.3v and 5V
• Provides several electronic building block interfaces
• Drive mode setting - the drive mode can be set via the jumper cap
• Includes two types of wiring, including connection terminals and pins
• Drive current can be adjusted by the potentiometer
