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.
Ra-01,Ra-02 operating frequency 433m, mainly for 433M CIDR block in the region, including
china and parts of south-east Asia.
