Product Description

• 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 a strong ability of anti-jamming and has the function of air wake-up Consumption. It can be covering thousands of people in the district environment, particularly suitable for meter reading, smart homes, burglar alarm equipment.
• The LoRa series module Ra-02 is designed and developed by AI-THINKER Technology. The SX1278 RF module is mainly used for long-range spread spectrum communication. It can resist Minimize current consumption. Thanks to SEMTECH’s patented LoRa™ modulation technology, the SX1278 has a high sensitivity of -148 dBm with a power output of +18 dBm, a long transmission distance, and high reliability.
• At the same time, compared with the traditional modulation technology, LoRa™ modulation technology has obvious advantages in anti-blocking and selection, which solves the problem that the traditional design scheme can not consider the distance, interference, and power consumption at the same time.
