We will be closed on November 25, 2021 and November 26, 2021 in observance of the Thanksgiving holiday. We will resume normal operations on November 29, 2021. Wishing you a safe and happy holiday from all your friends at SparkFun!
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). The EasyDriver requires a 7V to 20V 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. On this version (v4.4) we fixed the silk error on the min/max adjustment.
This is the newest version of EasyDriver V4 co-designed with Brian Schmalz. It provides much more flexibility and control over your stepper motor, when compared to older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the microstepping resolution. The sleep and enable pins are also broken out for further control.

This driver will be replacing what we use now, for eighth of the price.
Still in development of my project, but it is working. Worked first time I turned it on. Very easy to use. Surprised how hot the IC gets, but not excessive.
I am not an end user but having paced large orders for the previous version and 50 of this item, I think I can say with assurance that these are working great for their intended use.
I bought the EasyDriver and later the Big EasyDriver to mess around with some stepper motors for a camera slider. The drivers are super easy to work with and easy to set up. I am slowly learning the rest of the process such as Arduino code and what not but I'll getting there! Thanks Sparkfun!
Easy to set up. I first built a basic shell script and ran it off of my Minniowboard Max:
Eventually I may to something constructive with it!
Also tried with Raspberry Pi, and no problem at all. Interface is easy.
I do worry about the chip temperature. So I ordering heat sink and paste. It way easy to setup and run, very nice thanks.
