AKCP LORA_RADIO_MODULE Manual 1. Introduction AKCP_LORA_RADIO_MODULE integrates Semtech RF transceiver chip SX1276, which adopts LoRa® 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 crowded frequency environment; it comes with strong anti-interference performance.
