433M Lora Ra-02
Description:
Ra-02 is based on SX1278 wireless transparent transmission module (transceiver one), with IPEX 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 enviroment with thousands of people,especially for meter reading, smart home, burglar alarm and other equipment.
