Description of EasyDriver Stepper Motor Driver China The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor. The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you've got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors. Note: Do not connect or disconnect a motor while the driver is energized. This will cause permanent damage to the A3967 IC and void our 3 days warranty. This module is the low cost chinese variant of EasyDriver from sparkfun. Usage instruction is available from sparkfun website (click here).
