LoRa series modules (Ra - 01 / Ra - 02) by essence can design and development of science and technology, this series of module
theRf chip SX1278 mainly adopts LoRa ™ remote modems, used for long distance spread spectrum communication
The letter,Resistance toInterfere with strong sex, can maximum limit reduce current consumption.With SEMTECH LoRa ™ are designed
The modulationTechnology, with more than 148 DBM SX1278 high sensitivity, + 20 DBM power output
, the transport distanceFrom far and high reliability.At the same time, relative to the traditional modulation technology, LoRa ™ modulation technology in the fight
Blocking and chooseAlso has obvious advantage, solve the traditional design scheme can't both distance,
Anti-interference and power consumptionThe problem.Ra, the Ra - 01-02 working frequency 433 m, mainly aimed at 433 m
Segment of the region, includingChina and southeast Asia.
