SX1278 LoRa module Anxinke LORA spread spectrum wireless module RA-02

 

The SX1278 LoRa spread spectrum wireless module uses the Enxin LoRa series module Ra-02. The interface is compatible with the NRF24L01 module. If you want to transfer data over long distances, you can directly replace the NRF24L01. Just change the program and do not need to change the hardware design.

Anxin LoRa series module (Ra-01/Ra-02) was designed and developed by Anxinke Technology, the module of this seriesRF chip The SX1278 mainly uses a LoRa? ? remote modem for ultra long-range spread spectrum communication. Strong anti-interference ability to minimize current consumption. Patented by LoRa? ? by SEMTECHTechnology, SX1278 has a high sensitivity of over -148dBm, +20dBm power output, transmission distanceFar away, high reliability. At the same time, compared to traditional modulation techniques, LoRa? ? modulation technology is anti-blocking and selection. The aspect also has obvious advantages, which solves the problem that the traditional design scheme cannot balance distance, anti-interference and power consumption at the same time. The problem. Ra-01, Ra-02 operating frequency 433M, mainly for the 433M network segment, includingChina and Southeast Asia.
