1. Product Overview

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 LoRaTM, SX1276 with -148dBm high sensititive

，

long range transmission, high

reliablity. 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

irrigation system.
