Product Descriptions：

The SX1278 LoRa spread spectrum wireless module adopts the Anxinke LoRa series module Ra-02 The exported interface is compatible with the NRF24L01 module. If you want to transmit data over long distances, you can directly replace NRF24L01 by changing the program without changing the hardware design.

Anxinke LoRa series modules (Ra-01/Ra-02), the RF chip SX1278 of this series module mainly uses LoRa ? Remote modem, used for ultra long distance spread spectrum communication, has strong anti-interference ability and can minimize current consumption. Utilizing SEMTECH's LoRa ? With patented modulation technology, the SX1278 has high sensitivity exceeding -148dBm, power output of+20dBm, long transmission distance, and high reliability. Meanwhile, compared to traditional modulation techniques, LoRa ? Modulation technology also has significant advantages in anti blocking and selection, solving the problem that traditional design schemes cannot simultaneously consider distance, anti-interference, and power consumption. Ra-01 and Ra-02 operate at a frequency of 433M, mainly targeting regions in the 433M network segment, including China and Southeast Asia.
