TECNOIOT TTL to RS485 Module

TTL Turn RS485 Module 485 to Serial UART Level Mutual Conversion Hardware Automatic

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 1000m of the 850m of 2 x 1.5 cable to do the test, it is recommended to use within 800m, more than 800m, 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. Support multi-machine communication, allowing access to up to 128 devices on the bus. Large area of copper, to prevent signal interference. Half-hole process design, thickness 0.8mm, can be easily used as a mother board, but also welding terminal use. With RXD, TXD signal indicator. 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:
