Ai-Thinker lora Series Module (Ra-01H) designed and developed by Ai-Thinker. This module is used for long distance spread spectrum communication.. Its RF chip SX1276 (as show as figure 1) Mainly. used LoRa 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 LoRa SX1276 with -148dBm high sensitive, with +20dBm power output, long range transmission, high reliability. Meantime, relative traditional modulation technique. LoRa 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
