RA-02 with IPEX external antenna
Description:
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 transfer data over long distances, you can directly replace the NRF24L01. Just change the program and do not need to change the hardware design.
Anxin LoRa series module (Ra-01/Ra-02), the RF chip SX1278 of this series mainly uses LoRa 6 4 remote modem for ultra long-range spread spectrum communication, which has strong anti-interference and can minimize Current consumption. With SEMTECH's LoRa 6 4 patented modulation technology, the SX1278 has a high sensitivity of over -148dBm, +20dBm power output, long transmission distance and high reliability. At the same time, compared with the traditional modulation technology, LoRa 6 4 modulation technology also has obvious advantages in anti-blocking and selection, and solves the problem that the traditional design scheme can not take into consideration the distance, anti-interference and power consumption at the same time. Ra-01, Ra-02 operating frequency 433M, mainly for the 433M network segment, including China and Southeast Asia.
