Overview
This is an industrial expansion module Raspberry Pi Compute Module 4 Lite/eMMC series module, with UPS module.
It features common interfaces such as Gigabit Ethernet, HDMI, USB, and GPIO, allowing additional 4G / 5G wireless communication modules to be connected via the M.2 or Mini-PCIe socket. There are also industrial interfaces/resources including RS485, CAN, and RTC.
Combined with the industrial rail-mount protection case, the module is an ideal choice for building IoT gateway, 4G/5G router, IoT data acquisition, or even the PLC device in the industrial automatic control system, and more.
Uninterruptible Power: It is able to charge the batteries and provide power output at the same time from external power supply. Automatically switch over to batteries output if external power supply is unavailable, keeps the system running without any trouble
