SX1278 LoRa Module 433M 10KM Ra-02

SX1278 LoRa Module 433M 10KM Ra-02.

The Ra-02 module is a wireless transmission module based on SEMTECH's SX1278 wireless transceiver. It uses advanced LoRa spread spectrum technology, with a communication distance of 10,000 meters. The SX1278 RF module is used primarily for long-range spread spectrum communication. The SX1278 has a high sensitivity of -148 dBm with a power output of +20 dBm, a long transmission distance, and high reliability. At the same time, compared with the traditional modulation technology, LoRa ™ modulation technology has distinct advantages in anti-blocking and selection, which solves the problem that the conventional design scheme cannot consider the distance, interference, and power consumption at the same time.
