LORA wireless module RA-02 with backboard

LoRa series module (Ra-01/Ra-02), the RF chip SX1278 of this series module mainly uses LoRa™ remote modem for ultra-long distance spread spectrum communication, strong anti-interference, can minimize current consumption. With SEMTECH's patented LoRa™ modulation technology, the SX1278 has a high sensitivity of over -148 DBM, 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 simultaneously take into account distance, anti-interference and power consumption. Ra-01 and Ra-02 operate at a frequency of 433M and are mainly targeted at areas in the 433M network segment, including China and Southeast Asia.
