Description:
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 a 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 SEMTECHs LoRa ™ patent modulation technique. Meanwhile, compared with the traditional modulation technology, LoRa ™ provides significant advantages in both blocking and selectivity over conventional modulation techniques.
It solves the problem of simultaneously balancing 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.
