rf-92uh module is a lora spread spectrum module based on sx1276 chip of semtech company. uart, 3.3v ttl level output. working frequency: 900mhz-931mhz. compared with the traditional rf technology, lora spread spectrum technology has the characteristics of centralized power density, strong anti-interference ability, strong security and long transmission distance.

  • transmit power: 20dbm
  • support agreement: lora
  • communication distance: 3km
  • core programme: sx1276
  • core strengths: full frequency coverage,uart transparent transmission

3000 meters sx1278 low power consumption 900mhz---931mhz lora module for lora meters

 

rf-star rf-92uhup module is a lora spread spectrum module based on the semtech sx1278 chip. wireless serial port transmission module (uart), 3.3v ttl level output. working frequency band 900mhz---931mhz. compared with traditional radio frequency technology, lora spread spectrum technology has the characteristics of concentrated power density, strong anti-interference ability, strong confidentiality and longer transmission distance. it meets battery power requirements and suitable for applications with ultra-low power consumption.
