Specifications
LoRa1278 adopts Semtech RF transceiver chip SX1278, which adopts LoRa TM Spread Spectrum modulation frequency hopping technique. The features of long distance and high sensitivity (-139 dBm) make this module perform better than FSK and GFSK module. Multi-signal won’t affect each other even in crowd frequency environment; it comes with strong anti-interference performance.
