Description
The
Ra-02 is a wireless transmission module based on SemTech's SX1278 wireless transceiver. The SX1278 RF module is mainly used for long-range spread spectrum communication. This adopts advanced LoRa spread spectrum technology, with a communication distance of 10Km. It has strong ability of anti-jamming and has the function of air wake-up. The module can be covering many people in a wide district area, particularly suitable for meter reading, smart home, security alarm equipments and more. This module can work by minimum current consumption. The SX1278 has a high sensitivity of -148dBm with a power output of +18dBm, a long transmission distance and high reliability. At the same time, compared with the traditional modulation technology, The AI-Thinker modulation technology has obvious advantages in anti-blocking and frequency selection, which solves the problem of traditional design scheme which can not consider the long distance, interference and power consumption at the same time.
