Description
RA-02 SX1278 433MHz LoRa Wireless Module
The RA-02 is an RF module based on the SX1278 transceiver and LoRa spread-spectrum modulation. The source advertises a 10,000m communication distance. This is a seller-stated figure, not a guaranteed operating range; results depend on antenna, line of sight, installation, interference, regional radio regulations and configuration.
The listing describes long-range, low-current wireless communication and suggests meter reading, smart-home and alarm equipment applications. It also claims +20dBm (100mW) transmit output and sensitivity down to −148dBm; actual performance depends on the complete radio design.
