Feature : Working Voltage: 5V Main Chip: MAX485 Speeds: up to 2.5Mbit/Sec Distances: up to 1200 meters Multi-drop Supports: up to 32 devices on same bus Uses differential signaling for noise immunity On board 5.08(mm) 2P connector for RS 485 wires All the pins of the chip are brought out, can be controlled by MCUPIN: VCC: 5V A: Non-inverting receiver input and no-ninverting driver output B: Inverting receiver input and inverting driver output GND: 0V R0: Receiver output (to rx pin of micro controller) RE: Receiver output enable (low to enable) DE: Driver output enable (high to enable) DI: Driver input (to Tx pin of micro controller)

?Application?: Use to Low-Power RS-485 Transceivers, Low-Power RS-422 Transceivers, Level Translators, Transceivers for EMI-Sensitive Applications, Industrial-Control Local Area Networks. ?Data connections to the modules are provided by a standard 0.1" pitch header pins which can also be connected into standard prototyping PCB and breadboards. Screw terminals provide convention connection to the actual data cable. ?Can 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. ?The low power transceiver module is based on the MAX485 IC to allow serial communication over very long cable runs (up 4000 feet / 1200 meters). ?Serial data can be transmitted in both directions (half duplex) at a data rate up to 2.5Mbps.
