Industrial IoT Wireless Expansion Module Designed For Raspberry Pi Compute Module 4

Industrial IoT Module Based On CM4

Suitable For IoT Applications Like IoT Getaway, Wireless Router, Intelligent Data Acquisition...

4G/5G/LoRa Support, Multi Interfaces

 This is an industrial expansion module based on Raspberry Pi CM4, which features common interfaces such as Gigabit Ethernet, HDMI, USB, and GPIO, allows additional 4G / 5G / LoRa 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 industrial automatic control system, and more.
