SX1278 Ra-02 LoRa Module 433Mhz

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 up to even 15km. Of course, this is under optimal conditions without buildings or forests. In practice, a distance of 2km is easily achievable.

It has strong anti-jamming capability 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 high sensitivity of -148 dBm with an output power of +20 dBm and a long transmission distance and high reliability. At the same time, LoRa™ modulation technology, compared with traditional modulation technology, has clear advantages in blocking and selection, solving the problem that traditional design cannot take distance, interference and power consumption into account at the same time.
