LoRa series module Ra-01Sc is designed and developed by Shenzhen Ai-Thinker Technology Co., Ltd. This module is used for ultra-long distance spread spectrum communication. Its RF chip LLCC68 mainly uses LoRa remote modem for ultra-long distance spread spectrum communication, with strong anti-interference and low power consumption. LLCC68 chip has a high sensitivity of over-129 dBm, a 20 dBm power output, a long transmission distance and a high reliability with SEMTECH's LoRa patent modulation technique. Meanwhile, comparing with the traditional modulation technology, LoRa provides significant advantages in both blocking and selectivity over conventional modulation techniques. It solves the problem of simultaneously balance the distance, the anti-interference and the power consumption which the traditional design scheme can’t achieve.

Application areas:

automatic meter reading, supply chain and logistics, home building automation, security system, remote irrigation system.
