Description

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.

LoRa series module (Ra-01/Ra-02), the module of this seriesRF chip SX1278 mainly uses LoRaTM remote modem for ultra long-range spread spectrum communication.Strong anti-interference ability to minimize current consumption. LoRa modulation with 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, LoRaTM 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 SX1278 features:
