This Ai Thinker LoRa Series Ra-02 Spread Spectrum Wireless Module 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. Can be covering thousands of people in the district environment, particularly suitable for meter reading, smart home, burglar alarm equipment.

The LoRa series module Ra-01 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 +20 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 cannot consider the distance, interference and power consumption at the same time.

    Seems good, well packed.
    Note that the module is notoriously hard to solder to, and requires an antenna for stable working (NOT included here)
