TTL to RS485 Mutual Converter 3.3V/5V Hardware Automatic Flow Direction Control Converter Module

Description

TTL to RS485 Converter Module 3.3V 5V Two Way Communication EMC EMI RXD TXD Anti Interference Lightning for Arduino AVRThe power supply of this product is wide voltage (3.0V ~ 30V), 3.3V system and 5.0V system compatible, 3.3V and 5.0V signals can match. This product with a terminal block and silicone wire, direct wiring use, all imported original chip, powerful, lightning protection design, anti-interference ability, industrial, quality assurance 1 year!This transmission module to achieve the TTL signal and RS485 signal interchange, but we must know, 485 is half duplex communication, this communication can achieve two-way communication, but not in both directions at the same time, must Alternately; that is, each section of the communication channel can be either a transmitting end or a receiving end, but at the same time, the information can have only one transmission direction.To achieve the RS485 signal automatic flow control, send and receive direction automatically switch, use this module with your operation as simple as the serial portBaud rate: 110 ~ 256000bpsModule Highlights:(1) wide voltage power supply (3.0V ~ 30V), the limit voltage of 33V, it is recommended to use within 30V, the minimum voltage is higher than 2.8V. (2) compatible with 3.3V and 5.0V signals, can match the module (3) has a very high EMC and EMI performance. (4) the use of imported chips, industrial design, anti-interference ability, while the use of powerful 485 lightning design, industrial and fi
