Overview
The Inventory Master compact design entry-level IoT router built for industrial applications, such as vending machines, ATM, Kiosk, IP camera, digital signage, EV charging point, water treatment, solar panel power, etc. It provides high speed 4G LTE or dual mode LTE-M/NB-IoT for applications that require different data throughput. it has 2-RJ45, 1RS232, 1-RS485, WIFI, GNSS, and it is perfect for connecting the ethernet IP and serial port devices to cloud via cellular network. Besides, its auto switchover between wireless and wired WAN, multiple VPN features provide robust and secure connectivity for data transmission. In addition, OpenWrt based Linux OS industrial IoT router, which provides C/C++, Python programmable embedded environment for IoT developers and programmers to implement their industrial applications in a flexible and fast way.
