Description:
Ra-01S-P is a LoRa series module designed and developed by Shenzhen Ai-Thinker
Technology Co., Ltd. This module is used for ultra-long distance spread spectrum communication. Its RF chip SX1268 mainly uses a LoRa™ long-range modem for ultra-long distance spread spectrum communication, with strong anti-interference and the ability to minimize current consumption. With the help of SEMTECH's LoRa™ patented modulation technology.
The module has a built-in power amplifier (PA) and low-noise amplifier (LNA) on this basis, with a high sensitivity of more than -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.
