Ra-02 SX1278 was designed as a wireless transmission module based on SEMTECH’s SX1278 wireless transceiver. It Utilizes the advantages of advanced LoRa spread spectrum technology, offering a communication distance of 10,000 meters. It provides a strong ability of anti-jamming and has the function of air wake-up Consumption. The SX1278 RF module is widely used for long-range spread spectrum communication. And can also resist Minimizing current consumption. The SX1278 offers a high sensitivity of -148 dBm with an influence output of +20 dBm. And an extended transmission distance and high reliability. At a similar time, compared with the normal modulation technology, LoRa â„¢ modulation technology has obvious advantages in anti-blocking and selection, Thus solving the matter that the normal design scheme. Which can’t consider the distance, interference and power consumption at an equivalent time.
It often covers thousands of people in the district environment, particularly suitable for meter reading, smart home, burglar alarm equipment. This product was designed based on the WIFI Kit 32 added SX1278 chip, i.e. LoRa remote modem, 433MHz frequency, about -148dBm high sensitivity, +20 dBm power output. And also offers high reliability, transmission distance (measured open area communication distance 2.6Km).
