Level Conversion Serial Port Ttl To Rs485 To Serial Port Uart Module Mcu Automatic Flow Control In Pakistan



RSV automatic flow direction control module compatible with 3.3V and 5.0V power supply and signal No need to “receive-transmit” control, use this module is as simple as operating the serial port.


  1. Transmission distance up to kilometers. 
  2. Absolute adopts imported chip, industrial design, strong anti-interference ability, at the same time more effective lightning protection design, 485 can be used in industrial field and field under the harsh environment. (Using 850 meters with 2 * 1.5 cable to do the test, it is recommended to be used within the 800 meters, more than 800 m, please add extra repeaters). 
  3. Use half hole process design, the thickness of 0.8 mm, can be used easily as a child motherboard, also can be used welding terminals. 
  4. With a standard 2.54 spacing design, convenient your secondary development. 
  5. With 120 European match resistance, can make short sub R0 can match resistance, proposed the short answer the long-distance transport. 
  6. Support multiple machine communications, allowed to take in up to 128 devices on the bus. 
  7. This module can be a hot plug, there will be no other 485 chip hotplug phenomenon of a signal switch to death. 
  8. Large area laying copper, preventing signal interference. 

Module highlights:

  1.  Wide power supply range: 3.3V~5.5V
  2. 3.3V and 5.0V signal compatibility
  3. It adopts originally imported chip, industrial grade design, strong anti-interference ability, and adopts more effective 485 lightning protection design. It can be used in industrial and harsh environments, working temperature is -40 ° C to +85 ° C The transmission distance can reach up to a kilometer (using 850 meters of 2*1.5 cable for testing, it is recommended to use within 800 meters, more than 800 meters, please add repeater)
  4. Semi-hole process design, thickness 0.8mm, easy to use as a motherboard or solder terminal
  5. With RXD, TXD signal indicator, the receiving and receiving status is in full view
