Makes stepper motors easy.
Yep, it's an easydriver clone, with all the properties you'd expect from the original (well v4.4).The microstepping pins are pulled up which makes them not so easy to control from a microcontroller. Luckily you can remove the pull-up resistors, connect them to GPIOs, and drive them high if you do want microstepping.There are no heat sinks on the linear regulator so it gets very hot, especially if you're using it to also power a microcontroller (eg. Esp8266). Definitely put a heat sink on the A3967 and consider powering the low voltage side and your controller with a buck converter instead. I might have cooked the linear regulator stepping 24v down to 3.3v...All that aside, this is a fantastically easy way to drive stepper motors with a couple or three GPIOs per motor - only the step input is truly required to make any use of a stepper but you'll probably want to wire up the direction pin too.
