The Ra02 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 got 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, meter reading, smart home and burglar alarm apparatus.

The LoRa series module Ra01 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.
