Spread Spectrum Transmission Module

Specification

The LoRa 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. In addition, LoRaTM modulation technology is anti-blocking and selection compared to conventional modulation methods.

The aspect also offers clear benefits, which addresses the issue that the typical design approach cannot simultaneously manage distance, anti-interference, and power consumption. the issue. running at 433M, primarily for the 433M network section Ra-01, Ra-02. Module for Spectrum Transmission
