Overview

    LGW is a gateway integrating Lora, WIFI, 4G/LTE, LAN/WAN interfaces. The WI-FI module adopt MT7688AN as module core chipset. The operating system of WI-FI module could be ether Linux or OpenWRT. The LoRa module adopt SX1262 as core chipset. There is a mPCIe slot for adopting 4G/LTE mPCIe card. The mPCIe slot connect to the USB port of WIFI module and act as a 4G/LTE network card under associated Linux driver. There are RS485, DI and DO interface connect to WIFI module that could be used to connect peripheral devices.
