If you need to control some stepper motors for a 3d printer or a CNC machine, you need a stepper motor driver. Usually, these come with parallel port connectivity and if you don’t have a parallel port on your PC or you want to drive your CNC machine from a Raspberry Pi, then you have the choice of either using a USB to parallel adapter, or you can use a microcontroller.
A friend purchased a chinese stepper driver based on the TB6560 and needed a way to run the steppers from an arduino, so I made a shield for this purpose.
The design is made in Eagle using the pinout information of the stepper driver from this website.
