The 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 strong anti-interference capability and features air wake-up consumption. It can cover thousands of people in the area environment, making it particularly suitable for meter reading, smart home, and burglar alarm equipment. The LoRa Ra-01 series module is designed and developed by AI-THINKER technology. The RF SX1278 module is mainly used for long-range wide-spectrum communication. It can resist minimizing current consumption. Thanks to Semtech's patented LoRa modulation technology, the SX1278 has high sensitivity of -148 dBm with an output power of +20 dBm, long transmission distance, and high reliability. At the same time, compared to traditional modulation technology, LoRa modulation technology has obvious advantages in anti-blocking and selection, solving the problem that traditional design cannot take into account distance, interference, and power consumption simultaneously.
