SX1278 LoRa Module Ra- 02 433MHZ Wireless Spread Spectrum Transmission

SX1278 LoRa Module Ra- 02 433MHZ Wireless Spread Spectrum Transmission

The Ra-02 is a wireless transceiver module that utilizes SEMTECH’s SX1278 chip. It employs advanced LoRa spread spectrum technology, enabling communication over distances up to 10,000 meters. With robust anti-interference features and support for low-power air wake-up functions, it’s well-suited for long-range communications. The SX1278 RF module is optimized for extended reach and efficiency, offering a sensitivity of -148 dBm and an output power of 20 dBm to ensure reliable long-distance transmission. LoRa™ modulation technology surpasses traditional methods in anti-blocking and selectivity, effectively balancing the trade-offs between distance, interference, and power consumption found in standard designs. This module’s capacity to connect thousands of devices within a district makes it perfect for meter reading, smart home, and burglar alarm system applications.
