RS485 to TTL Converter Module Serial Port UART Hardware Automatic Flow Control Module

RS485 to TTL Converter Module Serial Port UART Hardware Automatic Flow Control Module is based on MAX485 chip, which is one of the most relied on when working with the RS485 Bus. This module supports 3.3V and 5V power supplies, and TTL Levels. It can connect and identify up to 128 nodes on the RS485 bus. This module also supports a very long range of the bus.

This RS485 to TTL Converter Module can support up to 800 metre of bus length. It has connections for RX, TX, +ve, and GND on one side, and on the other side, it has connection for RS485 bus. It also has the Indicators for the Receive and Transmit Signals. The thickness of the PCB is 0.8 mm, which enables it to be used as an add-on on any of your PCBs or devices.

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, which can play a very good anti-jamming and anti-effect, making it more secure; it can be left unconnected when used indoors for short-distance transmission.
• Using the standard 2.54 pitch design, easy secondary development.
• Has a 120 ohm termination resistor, 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.
• 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 environments. The working temperature is -40° to +85° with a transmission distance up to 1 kilometer (tested with 850 meters of cable F1.5, recommended up to 800 meters, beyond which repeaters should be added).
• Semi-hole pads, onboard module, thin PCB, with a thickness of 0.8mm.
• Has RXD, TXD signal indicator lights to monitor send and receive status.

Note:

• 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.
