TECNOIOT 5 pieces TTL RS485 485 to Serial UART Mutual Conversion Automatic Flow Control

• RS485TTL This module realizes the mutual conversion between TTL signal and RS485 signal, no need for send control, use this module when you operate the serial port so simple, compatible with 3.3V and 5.0V power supply, compatible with 3.3V and 5.0V signal; Imported chip, the performance is very stable, in line with industrial design standards;
• Design compact Anti interference ability, while more effective 485 mine design, in the industrial field and on site 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 repeater .
• Easy Operation Adhere to the 485 bus lightning protection design and anti jamming design, long distance transmission in the field, the module 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.
• Description The use of standard 2.54 pitch design to facilitate your secondary development. With 120 ohm matching resistance
• Description shorted R0 to allow matching resistance, remote transmission of the proposed short circuit.

x5pcs TTL Turn RS485 Module 485 to Serial UART Level Mutual Conversion Hardware Automatic Tips: 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; Imported chip, the performance is very stable, to industrial design standards; 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 do the test, it is recommended to use within 800 meters, more than 800 meters, please add repeaters). Product Features: 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. Product parameters: Operating voltage: compatible with 3.3V and 5.0V Support baud rate: 110-256000bps Operating temperature: -40 Celsius to +85 Celsius Communication signal: compatible with 3.3V and 5.0V Packet Contains: 5pcs x TTL Turn RS485 Module
