Description
Ra-02 is based on SX1278 wireless transparent transmission module (transceiver one), socket it can connect external antenna. Using advanced LoRa spread spectrum technology, communication distance is10000 meters, super error correction, anti-interference ability, with the air wake-up function (ultra-low power consumption). It can be used in the environment with thousands of people, especially for meter reading, smart home, burglar alarm and other equipment.
