SX1278 RA02 LoRa Module

The SX1278 RA-02 LoRa Module is a long-range wireless communication module based on the Semtech SX1278 transceiver chip and developed by Ai-Thinker. Operating primarily on the 433 MHz frequency band, the module uses LoRa spread spectrum technology to provide reliable, low-power, long-distance wireless communication for IoT and remote monitoring applications. It supports multiple modulation modes including LoRa, FSK, GFSK, and OOK, making it suitable for industrial automation, smart agriculture, wireless sensor networks, home automation, telemetry, and remote data transmission systems. The module communicates through an SPI interface and requires a 3.3V power supply.
