Description

This module is usedfor long distance spread spectrum communication.,Its RF chip SX1276(as show as figure 1)Mainly used LoRaTM remote modem , for ultra-long-distance spread spectrum communication , strong anti-interference , can minimize current consumption. With the help of the SEMTECH the patent technology of LoRaTM, SX1276 and SX1278 with -148dBm high sensititive,with +20dBm power output, long range transmission, high reliablity. Meantime , relative traditional modulation technique , LoRa TM modulation technique has obvious advantages in anti-blocking and selection, It solves the problem that traditional design scheme can not consider distance, anti-interference and power consumption simultaneously. Its application can be automatic meter reading, home building automation, security system, remote irrigation system.
