The R256 single-axis controller and driver is engineered to feature the same compact size as its predecessor, yet is capable of increased microstepping resolution and higher output current. It is capable of step resolutions ranging from 2× to 256×, and it operates from +12 to 20V dc. Its phase current ranges from 0.1 to 2A peak. It is designed to be programmed via serial port and used as a stand-alone unit with no PC connection required.
