Features

• 【RS485TTL】 This module realizes the mutual conversion between TTL signal and RS485 signal, no need to "receive - send" control, use this module as you operate the serial port as simple, compatible with 3.3V and 5.0V power supply, compatible with 3.3V and 5.0V signal.
• Has RXD, TXD signal indicator light, monitor send and receive status. Package Contains: 5 pcs TTL Turn RS485 module.
• Anti-interference ability, while more effective 485 mine design, in the industrial field and field harsh environment, the transmission distance of up to 1000 meters of the 850 meters of 2 * 1.5 cable to the test, it is recommended to use within 800 meters, more than 800 meters, please add repeaters).
• 【Easy operation】 Fully consider the 485 bus lightning protection design and anti-jamming design, long-distance transmission in the field, the module's "earth" side access to the earth, can play a very good anti-jamming and lightning effect, 485 Bus more secure; indoor short distance transmission can not access the earth.
• The use of standard 2.54 pitch design, to facilitate your secondary development. With 120 ohm matching resistor, shorted R0 to enable matching resistor, long-distance transmission of the proposed short-circuit.
