MAX485 RS-485 Interface ICThe MAX485 enables half-duplex RS-485 transmission up to 2.5Mbps. Simple to use and program this shield enables transmission and reception of data up to 4,000 feet. It operates from 5V (can be supplied from the Arduino Board). Many instruments use RS485 rather than RS232 transmission so this is an easy way to integrate Arduino with lab instruments. RS485 is the underlying ahardware protocol for DMX. So it can also be used to control lighting and sound circuits that use DMX.MAX485 Integrated CircuitConnection speed: up to 2.5 MbpsHalf-duplex transmission
