DORHEA 12Pcs MAX485 Transceiver Module TTL UART Serial to RS485 Instrument Interface Module Max458 Chip RS-485 Communication Transceiver 5V SCM Development Board Serial Adapters for Raspberry Pi

MAX485 chip is a low power consumption for RS-485 communication, draw between 120µA and 500µA of, limit the slew rate transceiver to allow serial communication over very long cable runs (up 4000 feet / 1200 meters). The 5.08 (mm) pitch 2P terminal, convenient RS-485 communication wiring.Chip leads all pins can be controlled through the microcontroller.. 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.. RS-485 module applicable to Low-Power RS-485 Transceivers, Low-Power RS-422 Transceivers, Level Translators, Transceivers for EMI-Sensitive Applications, Industrial-Control Local Area Networks.. Supply current when unloaded or fully loaded with disabled drivers. 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.. Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.
