SCM TTL to RS485 Adapter 485 to UART Serial Port 3.3V 5V Converter Level Module
100% brand new and high quality
100% brand new and high quality
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:
Compatible with 3.3V and 5.0V power supply
Compatible with 3.3V and 5.0V signal
Absolute using imported chips, industrial design, 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 ℃ to + 85 ℃ transmission 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)
Semi-hole pads, onboard module, thin PCB, having a thickness of 0.8mm
Has RXD, TXD signal indicator light, monitor send and receive status
Features:
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
Using the standard 2.54 pitch design, easy secondary development
Has a 120 ohm termination resistors, shorted R0 to enable the termination resistor
Support multi-machine communication, allowing access at up to 128 devices on the bus
The module can be hot swapped, the signal does not appear dead phenomenon
A large area of copper to prevent interference
