Features

• A3967 Microstepping Driver
• MS1 and MS2 pins jumper out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)
• Compatible with 4, 6, and 8 wire stepper motors of any voltage up to 30V
• Adjustable current control from 150mA/phase to 700mA/phase
• Power supply range for stepper motor from 6V to 30V. The higher the voltage, the higher the torque at high speeds

Step 1: Pin Definition

Step 2: Sample Hardware Connection

• Here are the pin connections from Arduino Uno to Easy Driver :

D2 -- STEP
D3 --DIR
D4 -- MS1
D5 -- MS2
D6 -- ENABLE

• and here are the pin connection from Stepper Motor to Easy Driver :

Green Wire -- A+
Red Wire -- A-
Blue Wire -- B+
Yellow Wire -- B-

• For push button, just connect one of the button's pin to arduino's pin (D8, D9 or D10 refer to the picture) and the other button's pin connect to the ground.
• To power up Easy Driver, the GND and +5v from Easy Driver are connected to the Arduino Uno's GND and +5v power pin.
  
  
• The Motor Power Supply will be connected to the M+ and GND of the Easy Driver. Make sure to connect the battery's polarity is correct, positive to the M+ and negative to the GND.
