The Ra-01SCH is a module from the LoRa series, crafted by Ai-Thinker Technology for ultra-long-range frequency communication. Its radio frequency chip, the LLCC68, primarily employs the LoRa™ remote modem for extensive range communication. This module boasts robust interference resistance and optimizes power consumption. Leveraging SEMTECH’s patented LoRa™ modulation technology, the LLCC68 achieves high sensitivity beyond -129dBm and a transmission power of +22dBm, ensuring long-range transmission and reliability. Moreover, LoRa™ modulation technology outperforms traditional methods by offering superior anti-blocking and selectivity, addressing the challenges of distance, interference, and power efficiency that conventional designs cannot simultaneously meet.
This module can be widely used in automatic meters reading, home building automation, security system, remote irrigation system, etc.
