3X SX1278 LoRa Module LoRa 02 433M Adapter Module Wireless Transmission SPI Communication Module Περιγραφή

The SX1278 LoRa spread spectrum wireless module uses the LoRa series module Ra-02. The interface is compatible with the NRF24L01 module. If you want to transmit data over long distances, you can directly replace the NRF24L01 by changing the program without changing the hardware design.
The RF chip SX1278 of the LoRa series module (Ra-01/Ra-02) mainly uses the LoRa long-range modem for ultra-long-distance spread spectrum communication, with strong anti-interference and the ability to minimize current consumption. With SEMTECH's LoRa patented modulation technology, the SX1278 has a high sensitivity of more than -148dBm, a power output of +20dBm, a long transmission distance and high reliability.
At the same , compared with traditional modulation technology, LoRa modulation technology also has obvious advantages in anti-blocking and selection, solving the problem that traditional design solutions cannot take into account distance, anti-interference and power consumption at the same . Ra-01, Ra-02 operating frequency 433M, mainly for areas with 433M network segments, including China and Southeast Asia.
