     The SX1278 based Ra-02 LoRa module is a spread spectrum communication module designed for long range and low power consumption wireless data transmission. It uses the SEMTECH SX1278 RF chip and is manufactured by Ai-Thinker (Anxinke). It has an interface compatible with the NRF24L01 pin layout, so it can be used in existing designs with a software update without any hardware change.

     It operates in the 433MHz frequency band. Thanks to LoRa modulation technology, it offers high receiver sensitivity and strong interference immunity. It is suitable for very long range communication applications in open area conditions.
