The series of modules RF chip SX1278 mainly uses LoRa remote modem for ultra-long distance spread Letter, strong anti-interference, to minimize current consumption. With the help of SEMTECH's LoRa ™Lee modulation technology, SX1278 has a high sensitivity of more than -148dBm, +20dBm power output,Transmission distance, high reliability. At the same time, relative to the traditional modulation technology, LoRa modulation technology in the anti-Blocking and selection also has a clear advantage to solve the traditional design can not take into account the distance,Anti-jamming and power consumption problems. Ra-01, Ra-02 operating frequency of 410-525MHz, support for China and Southeast Asia.
