Raspberry Pi Compute Module 4 Industrial IoT Mini-Computer (20970)

The Raspberry PiCompute Module 4 Industrial IoT Module (20970 ) is an industrial expansion module based on the Raspberry Pi CM4 that features common interfaces such as Gigabit Ethernet, HDMI, USB, and GPIO, and allows you to connect additional 4G/5G/LoRa wireless communication modules via an M.2 or Mini-PCIe connector. There are also industrial interfaces/resources including RS485, CAN, and RTC. Combined with a housing designed for industrial DIN rail mounting, this module is the perfect choice for creating an IoT gateway, 4G/5G router, IoT data collection, or even a PLC device in an industrial automatic control system, and much more.

Application option:

Connecting to the Raspberry Pi CM4 computing module
Standard CM4 connector and partial Raspberry Pi GPIO connector
Suitable for 4 Lite computing module/EMMC series module

Supports 4G/5G/LoRa wireless modules
Built-in M.2 slot that comes with a Mini-PCIe adapter,
Compatible with 4G/5G/LoRa wireless modules with M.2 or Mini-PCIe interface

An additional communication module is required to enable 5G/4G/3G/2G cellular network or LoRa gateway function. It is recommended to use: SIM7600G-H-M.2, SIM8202G-M2, SIM8200EA-M2, SIM7600G-H-PCIE, SX1302 868M LoRaWAN Gateway

Interfaces.

The design provides a reserved space for the heat dissipation system. Radiator and cooling fan are NOT included in the module package.

The protective ABS plastic housing supports the ability to mount the module on a DIN rail, which provides easy installation and safer operation.
