Axiomtek LoRa series module Ra-01SC is designed and developed by Shenzhen Axiomtek Technology Co. The module is used for ultra-long-range spread spectrum communication, and its RF chip LLCC68 mainly adopts LoRa remote modem for ultra-long-range spread spectrum communication with high interference immunity and low power consumption. With SEMTECH’s patented LoRa modulation technology, LLCC68 has a high sensitivity of over -129dBm and a power output of +22dBm, with long transmission distance and high reliability. The LoRa modulation technology also offers significant advantages in anti-blocking and selectivity compared to traditional modulation technologies, solving the problem of traditional design solutions that cannot balance distance, interference immunity and power consumption at the same time. Application areas are for Smart meters, supply chain and logistics, home building automation, security systems, remote irrigation systems, etc.
