Ai Thinker LoRa Ra-02 SX1278 433MHz Wireless Spread Spectrum Transmission Module is a wireless transmission module based on SEMTECH SX1278 wireless transceiver. It adopts advanced LoRa spread spectrum technology, with a communication distance of 10,000 meters. It has strong anti-jamming ability and has the function of air-alarm clock-up Consumption. can be covering thousands of people in the neighborhood environment, especially suitable for reading counters, smart home, alarm equipment.

The LoRa series module Ra-01 is designed and developed by AI-THINKER Technology. The SX1278 RF module is mainly used for long-range spread spectrum communication. It can withstand Minimize power consumption. Thanks to SEMTECH's patented LoRa ™ modulation technology, the SX1278 has a high sensitivity of -148 dBm with a power of + 20 dBm, a long transmission distance and high reliability. At the same time, compared to 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.
