DFRobot RS485 MAX485ESA - Shield for Arduino

Shield forArduinothat allows data transfer via RS485 Protocol. Despite the fact that the RS485 is anarchaic bus, it has some features that distinguish it from the newer interfaces. It allows, i.a. to connect up to 32 devices on one line with the width of up to 1 km with a maximum speed up to 10 MB/sec.
