SX1278 LoRa Spread Spectrum Wireless Module / 433 MHZ/SPI Interface theRf chip SX1278 mainly adopts LoRa remote modems, used compatible with long distance spread spectrum communication The letter,Resistance toInterfere with strong, can maximum limit reduce current consumption. 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, working frequency 433 m, mainly aimed at 433 m Color: As Shown Material: PCB Package Contents: 1*Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
