433Mhz Sx1278 Lora Module 433M

SX1278 LoRa Module Ra-02 Module
Description
SX1278 LoRa spread wireless module uses Anxin may LoRa series module Ra-02. Out of the interface-compatible NRF24L01 module, if you want to long-distance data transmission, can be directly replaced NRF24L01, as long as the change program and you do not need to change the hardware design.

The series modules

the radio-frequency chip SX1278 mainly adopts LoRa remote modem for ultra-long-distance spread communication,

strong anti-interference, it is possible to minimize current consumption. With the help of SEMTECH LoRaPatent modulation

technology SX1278 has over-148dBm high sensitivity of the + 20dBm the power output from the transmission distance

from far and high reliability. At the same time, compared with the traditional modulation technique LoRa modulation technology in the anti-blocking and selection

also has obvious advantages, to solve the traditional design scheme cannot go hand in hand distance, strong anti-interference and power consumption

the problem.
