  • LoRa Ra-02 SX1278 433MHz Wireless Spread Spectrum Transmission Module
  • Can cover thousands of people in the district environment, particularly suitable for meter reading, smart home, burglar alarm equipment.
  • At the same time, compared with the traditional modulation technology, LoRa modulation technology has obvious advantages in anti-blocking and selection, which solves the problem that the traditional design scheme can not consider the distance, interference, and power consumption at the same time.
  • Ra-02 is a wireless transmission module based on SEMTECH’s SX1278 wireless transceiver.
  • It adopts advanced LoRa spread spectrum technology, with a communication distance of 10,000 meters.
  • It has a strong ability of anti-jamming and has the function of air wake-up Consumption.
  • The SX1278 RF module is mainly used for long-range spread spectrum communication.
  • the SX1278 has a high sensitivity of -148 dBm with a power output of +20 dBm, a long transmission distance, and high reliability.
