The SX1278 LoRa RA-02 433MHz Wireless Spread Spectrum Transmission Module is designed for long-range, low-power wireless communication applications.
Based on the Semtech SX1278 transceiver, the RA-02 uses LoRa Chirp Spread Spectrum (CSS) technology to provide high sensitivity and improved resistance to interference compared with many conventional wireless communication methods. The module supports SPI communication and can be interfaced with compatible microcontrollers and development boards.
The module operates in the 433MHz ISM band and is suitable for IoT, remote monitoring, sensor networks, automation, telemetry and other wireless communication projects.
The RA-02 provides high receiver sensitivity of up to approximately -148 dBm and supports programmable data rates. Depending on configuration and implementation, transmit power can reach up to +20 dBm.
