Description

TTL Turn To RS485 Module

Single-chip microcomputer, TTL turn RS485 module, 485 turn UART serial port, Level transfers, Hardware automatic flow control
Only one in the whole network, 3.3V, and 5.0V power supply, RS485 signal perfectly compatible with automatic flow control module. Without "Receiving - launch" control, this module is as simple to use with your serial port operations.

Highlights:
(1) Compatible with 3.3V and 5.0V power supply.
(2) Compatible with 3.3V and 5.0V signal.
(3) Absolute using imported chips, industrial design, and anti-interference ability, while using more effective mine design can be used in the industrial field and harsh field environments, the working temperature of -40°Cto +85°Ctransmission distance up to 1 kilometer (made with 850 meters of cable F1.5 tests recommended in the 800 meters, more than 800 m, please add repeaters).
(4) Semi-hole pads, onboard module, thin PCB, having a thickness of 0.8mm.
(5) Has RXD, TXD signal indicator light, monitor send and receive status.

Features:
(1) The module is fully considered mine design, long-distance transmission signal 485 in the wild, the module "Connected to the ground" terminal is connected to the earth, can play a very good anti-jamming and anti-lightning effect, more secure; it can not connect with the ground when the indoor short-distance transmission.
(2) Using the standard 2.54 pitch design, easy secondary development.
(3) Has a 120-ohm termination resistor, shorted RO to enable the termination resistor.
(4) Support multi-machine communication, allowing access to up to 128 devices on the bus
(5) The module can be hot-swapped, and the signal does not appear dead phenomenon.
(6) A large area of copper to prevent interference.
