Ai Thinker LoRa Series Ra-01S Spread Spectrum Wireless Module

Anxinke LoRa series modules (Ra-01S) are designed and developed by Anxinke Technology. This module is used for ultra-long-distance spread-spectrum communication. Its radio chip SX1268 mainly uses LoRa remote mode for ultra-long-distance spread-spectrum communication. It has strong anti-interference and can minimize current consumption. With SEMTECH’s LoRa patented modulation technology, SX1268 has a high sensitivity of over -148dBm, a power output of +22dBm, a long transmission distance, and high reliability. At the same time, compared to traditional modulation technology, LoRa modulation technology also has obvious advantages in anti-blocking and selection, which solves the problem of distance, anti-interference, and power consumption that traditional design solutions cannot simultaneously take into account. Application areas are used in automatic meter reading, home building automation, security systems, and remote irrigation systems.
