Ra-01SC Specification V1.1

1. Product Overview

LoRa series module Ra-01Sc is designed and developed by Shenzhen Ai-Thinker

Technology Co., Ltd. This module is used for ultra-long distance spread spectrum

communication. Its RF chip LLCC68 mainly uses LoRa ™ remote modem for ultra-long

distance spread spectrum communication, with strong anti-interference and low power

consumption. LLCC68 chip has a high sensitivity of over-129 dBm, a 20 dBm power output, a

long transmission distance and a high reliability with SEMTECH's LoRa ™ patent modulation

technique. Meanwhile, comparing with the traditional modulation technology,LoRa ™

provides significant advantages in both blocking and selectivity over conventional modulation

techniques. It solves the problem of simultaneously balance the distance, the anti-interference

and the power consumption which the traditional design scheme can’t achieve.

Application areas

automatic meter reading, supply chain and logistics, home building automation, security

system, remote irrigation system.
