I am currently using this drive to drive a small stepper motor that runs on 12V 1A. This driver could easily be connected to the Arduino Uno with up to three digital output pins and a ground connection. The driver is configured with a six-position DIP switch. The adjacent table lists all switch settings for microstepping and current limit. The I/O pins are clearly labeled so despite the lack of documentation, hookup was easy and I had no trouble hooking it up to the Arduino's power supply, motor, and controller. After a quick Google search I found a PDF document on the DFrobot website.
