TTL to RS485 Converter 3.3V/5.0V Hardware Automatic Control Converter Module For Arduino for Arduino AVR

 Feature:

1. Thunder & Interference Protection: Our TTL serial port to RS485 converter module is expertly designed with 485 bus Thunder protection and anti-interference features, ensuring exceptional EMC (Electromagnetic Compatibility) and EMI (Electromagnetic Interference) resistance. For outdoor long-distance transmissions, grounding the "Ground" terminal provides excellent interference resistance and Thunder protection, making the 485 bus more secure.

2. Versatile Grounding Options: The TTL to RS485 adapter module  offers flexible grounding options to suit different environments: ground it during long-range field communication for enhanced protection or simply leave it ungrounded for indoor, short-distance transmission, maintaining the integrity of your data signals either way.

3. Ease of Integration: Equipped with standard 2.54mm pitch pin headers, our TTL to RS485 converter is ready for seamless secondary development, bridging the between complex technology and your specific application needs. It's designed with DIY enthusiasts and professional developers in mind.

4. Built-In Termination Resistor: Features a 120 Ohm matching resistor, which can be easily engaged by shorting the R0 to ensure signal integrity over long distances. This small, yet critical feature is recommended for maintaining clear communication over extended ranges.

5. Multi-Node Communication: Our 485 to TTL single chip serial port converter  supports a multi-device network with the ability to connect at least 40 nodes without signal lock-up, ensuring a reliable communication array. It also allows hot-swapping, making it a flexible choice for systems that require constan

Specification:

Origin: Mainland China

Type: Module

Condition: New

Product size: 52.00x23.00x18.00mm

Product size: 2.05x0.91x0.71inch

Description:

The transparent transmission module realizes the mutual conversion of TTL signals and RS485 signals, but it is important to know that 485 is a half duplex communication method that can achieve bidirectional communication, but cannot be carried out simultaneously in both directions, and must be carried out alternately; That is to say, each segment of the communication channel can be the sender or receiver, but at the same time, information can only have one transmission direction.

Implemented automatic flow control of RS485 signals and automatic switching of receiving and sending directions. Using this module is as simple as operating a serial port
