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 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 '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 time, 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 time. Ra-01, Ra-02 operating frequency 433M, mainly for areas with 433M network segments, including China and Southeast Asia.
