Our RS-485 Serial Communications Module makes it easy to network up to 256 nodes together at distances up to 4,000 feet.  Each RS-485 node includes 3 screw-terminals for a 3-wire connection to the RS-485 master. Each RS-485 node includes a dedicated processor that communicates at 9600 baud on the RS-485 bus.  The RS-485 node module communicates at 115.2K baud to the host controller.  CE RS-485 nodes make use of the Texas Instruments SN65HVD12D RS-485 chip coupled with our own Atmel custom processor to ensure transparent RS-485 to USART conversion. On-board jumpers are used for configuration and network bus termination settings.  Supports host device baud rates of 9600, 19.2K, 38.4K, and 115.2K baud with a default host data rate of 115.2K baud.  Supports RS-485 Network Baud Rates of 9600, 19.2K, 38.4K, and 115.2K baud with a default RS-485 data rate of 9600 baud.

This RS485 module works with raspberry pi, particle photon, electron, onion omega, pycom, Arduino, Windows, Linux and with all major platform
