RDI403

1.Introduction

1.1Description

RDIx03 is a DTU of RS485-LoRaWAN independently developed by ManThink Technology Co. Ltd with highly flexible configuration and low power consumption. It is embedded with a high-performance MCU of NXP and a Radio chip SX127x of Semtech. It can get data from several slave devices by RS485 and uploading data to platform through LoRaWAN network.Users can quickly and flexibly configure DTU's working mode as needed,and quickly occupy the market.

1.2Applications

Industrial filed
Electricity IOT
Hydrometeorological monitoring
Environment protection, municipal administration engneer and other related scene

1.3Features
