SX1278 LoRa RA-02 + Antenna Ai-Thinker Wireless Transmission Board 433MHZ 10KM Original

Ai-Thinker LoRa Ra-02 SX1278 433MHz Wireless Spread Spectrum Transmission Module is a wireless transmission module based on the SEMTECH SX1278 wireless transceiver. It adopts advanced LoRa spread spectrum technology and supports a communication distance of up to 10,000 meters in suitable environments. The module is designed for low power consumption and provides robust anti-jamming performance for reliable long-range links. The LoRa series module Ra-02 is designed and developed by AI-THINKER Technology and the SX1278 RF chip is engineered for long-range spread spectrum communication. Using SEMTECH's patented LoRa™ modulation technology, the SX1278 achieves high sensitivity (reported to −148 dBm) while supporting output power up to +20 dBm, delivering extended transmission distance and improved link reliability compared with many traditional modulation schemes. LoRa™ modulation offers marked advantages in coexistence and interference resistance, addressing the competing demands of range, interference resilience and power efficiency in wireless system design. Typical application areas for the Ra-02 module include utility meter reading, smart home systems, alarm equipment and other IoT scenarios that require extended range and low power operation. The Ra-02 with antenna provides a compact, ready-to-deploy wireless transmission solution for developers and integrators seeking a long-range, low-power LoRa link based on the SX1278 platform.
