The MAX485 TTL to RS-485 Interface Module allows uCs to use the RS-485 differential signaling for robust long distance serial communications.
Long Distance: This low power transceiver module is based on the MAX485 IC to allow serial communication over very long cable runs (up 4000 feet / 1200 meters).
RS485 transceiver module Serial data can be transmitted in both directions (half duplex) at a data rate up to 2.5Mbps. It is possible to connect multiple modules together for communication between 2 or more devices(up to 32). For even greater distances two modules can be configured as a repeater.
Applications: Applicable to Low-Power RS-485 Transceivers, Low-Power RS-422 Transceivers, Level Translators, Transceivers for EMI-Sensitive Applications, Industrial-Control Local Area Networks.
EASY TO USE: Data connections to the modules are provided by a standard 0.1" pitch header pins which can also be soldered into standard prototyping PCB and breadboards. Screw terminals provide convention connection to the actual data cable.
