Ra-02 is a wireless transmission module based on the SEMTECH SX1278 wireless transceiver. It uses advanced LoRA spectrum technology, with a communication distance of 10,000 metres. It has a strong ability to prevent interference and has the function of air wake-up consumption. Can cover thousands of people around the environment, especially suitable for counters, smart home, burglary alarm equipment.
The module of the LoRa series Ra-01 was designed and developed by AI-THINKER technology. The SX1278 RF module is mainly used for wide-range range transmission spectrum communication. It resists minimal power consumption. Thanks to SEMTECHs patented LoRa modulation technology, the SX1278 has a high sensitivity of -148 dBm with an output power of +20 dBm, a long transmission distance and high reliability. At the same time, LoRa modulation technology has obvious advantages in anti-blocking and selection, which solves the problem that the traditional design scheme cannot take into account the distance, interference and power consumption.
