SX1278 Ra-02 LoRa Module 433Mhz (OT3206)

The Ra-02 is a wireless transmission module based on the SX1278 wireless transceiver from SEMTECH. It uses advanced LoRa spread spectrum technology, with a communication distance of 10km to even 15km. Of course, this is in optimal conditions without buildings and or forests. In practice, a distance of 2km is easily achievable.
It has a strong ability of anti-jamming and has the function of air wake-up Consumption. The SX1278 RF module is mainly used for long-range communication with a wide spectrum.
The SX1278 has a high sensitivity of -148 dBm with an output power of +20 dBm and a long transmission distance and high reliability. At the same time, compared with the traditional modulation technology, LoRa™ modulation technology has obvious advantages in blocking and selecting, which solves the problem that the traditional design cannot consider the distance, interference and power consumption at the same time.
