Description:

This LoRa Ra-01S module is used for ultra-long-distance spread-spectrum communication. LoRa Ra-01S radio chip SX1268 mainly uses LoRa remote mode for ultra-long-distance spread-spectrum communication. LoRa Ra-01S has strong anti-interference and can minimize current consumption. With SEMTECHs 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.
