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 features 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, a long transmission distance, and high reliability. At the same time, LoRa™ modulation technology, compared to traditional modulation technology, has clear advantages in blocking and selection, solving the problem that traditional designs cannot simultaneously account for distance, interference, and power consumption.
