Specification

TTL to RS485 module

3.3V and 5.0V power supply and signal compatible RS485 automatic flow control module does not need "receive-send" control, use
This module is as simple as operating a serial port. All imported chips are used, and the performance is very stable. Absolutely
Industrial grade design. The transparent transmission module realizes the mutual conversion between 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 done in both directions at the same time. must be alternated in turn; that is, each end of the communication
A channel can be a sender or a receiver, but information can only travel in one direction at a time. Baud rate: support
110~128000bps module highlights:

(1) Wide power supply range: 3.3V~5.5V

(2) Compatible with 3.3V and 5.0V signals

(3) use
Original imported chips, industrial-grade design, super anti-interference ability, more effective 485 lightning protection
Design, can be used in industrial sites and sites with harsh environments, the working temperature is -40°C to +85°C,
The transmission distance can reach kilometers

(4) Design with half-hole technology, plate thickness 0.8mm,
Can be conveniently used as a daughter board or as a solder terminal

(5) With RXD and TXD signal indicators,
Full view of sending and receiving status Visible module features:

(1) This module fully considers lightning protection
485 bus design and anti-interference design. When long-distance transmission in the field, connect the "ground" terminal
Module grounding can play a very good role in anti-interference and lightning protection. , making the 485 bus more secure; it is not
Grounding is required for indoor short-distance transmission.

(2) Adopt standard 2.54 pitch design
Convenient for your secondary development

(3) With 120 ohm matching resistance, the matching resistance can pass through
Short circuit R0. It is recommended to short-circuit for long-distance transmission.

(4) Support multi-machine
communication, allowing connection of up to 128 devices to the bus

(5) The module is hot-swappable and will not appear
The signal locking phenomenon that occurs when other 485 chips are hot-swapped.

(6) Large-area copper pouring to prevent signal
put one's oar in
