TTL to RS485 Converter Module 3.3V/5.0V Hardware Auto Control for Arduino AVR CG

Features: 

• TTL to RS485 module RS485 interchange TTL signal single chip serial port UART lightning protection hardware automatic flow control

• The 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 port

• Baud rate: 110 ~ 256000bps

Module Highlights:

• 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.

• Compatible with 3.3V and 5.0V signals, can match the module

• Has a very high EMC and EMI performance.

• The use of imported chips, industrial design, anti-interference ability, while the use of powerful 485 lightning design, industrial and field can be used in harsh environments, the working temperature of -40 ℃ to +85 ℃, transmission Distance up to kilometers (with 850 meters of 2 * 1.5 cable to do the test, it is recommended to use within 800 meters, more than 800 meters plus repeaters)

• With a terminal block and silicone wire, the use of very convenient.

• With RXD, TXD signal indicator, send and receive situation panoramic view.

• Factory direct, to ensure technical support and services, but also OEM and ODM.

Module Features:

• This module fully considered the 485 bus lightning protection design and anti-jamming design, high EMC, EMI performance, long-distance transmission in the field, the module "access to the earth" side access to the earth, can play well The anti-interference and lightning protection of the role of the 485 bus more secure; indoor short-distance transmission can not access the earth.

• With a standard 2.54 pitch pin, to facilitate your secondary development

• With 120 ohm matching resistance, shorted R0 can be enabled to match the resistance, long-distance transmission recommended shorted.

• Support multi-machine communication, the same network can connect at least 40 nodes.

• Can be hot-swappable, there will be no signal to death phenomenon.

• Anti-jamming alignment and copper way to prevent interference with the signal.

Package Includes:

• 1 x TTL to RS485 module
