TTL Fordítsa el az RS485 485-ös modult soros UART szintű kölcsönös átalakító hardver automatikus áramlásszabályozásra
TTL Turn RS485 Module 485 to Serial UART Level Mutual Conversion Hardware Automatic Flow Control
Product Description
Single chip microcomputer TTL to RS485 module 485 to serial port UART level mutual conversion Hardware automatic flow control

RS485 automatic flow control module compatible with 3.3V and 5.0V power and signal
No need to "receive-send" control, using this module is as easy as operating the serial port



This transparent transmission module realizes the mutual conversion of TTL signal and RS485 signal, but everyone must know that 485 is half-duplex communication. This communication method can realize two-way communication, but it cannot be carried out in both directions at the same time. Take turns alternately; that is, each end of the communication channel can be the sender or the receiver, but at the same time, information can only have one direction of transmission.
Baud rate: 110~256000bps, perfect support
Module highlights:
(1) Compatible with 3.3V and 5.0V power supply
(2) 3.3V and 5.0V signal compatible
(3) Absolutely adopt original imported chips, industrial-grade design, strong anti-interference ability, and adopt more effective 485 lightning protection design, which can be used in industrial sites and harsh environments in the field, and the working temperature is -40℃ to 85℃, the transmission distance can be up to kilometers (use 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 a repeater)
(4) The half-hole process design is adopted, and the thickness of the board is 0.8mm, which can be easily used as a mother board or as a solder terminal.
(5) With RXD and TXD signal indicators, you can have a panoramic view of the transceiver status
