Ra-01SC-P is a LoRa series module designed and developed by ShenzhenAi-Thinker Technology Co., Ltd. This module is used for ultra-long distance spread spectrum communication. Its RF chip LLCC68+ mainly uses LoRa™ long-range modem, which is used for ultra-long distance spread spectrum communication, has strong anti-interference ability, and can minimize current consumption. With the help of SEMTECH's LoRa™ patented modulation technology, the module has built-in power amplifier (PA) and low noise amplifier (LNA) on this technology, with high sensitivity exceeding-137dBm, +29dBm transmission power, long transmission distance and high reliability. At the same time, compared with traditional modulation technology, LoRa™ modulation technology also has obvious advantages in anti-blocking and selection, solving the problem that traditional design solutions cannot take into account distance, anti-interference and power consumption at the same time.It can be widely used in automatic meter reading, home building automation, security systems, remote irrigation systems, etc
