EDATEC CM4 Industrial is both a Raspberry Pi CM4 carrier board and a computer for industrial IoT, control, and automation that expands on the company’s CM4 Sensing and CM4 Nano solutions with more features and interfaces.

The system notably offers two RS485, one RS232, three analog inputs, two digital inputs, and one relay output through terminal blocks, as well as optional WiFi, Bluetooth, and 4G LTE + GPS connectivity, and a wide DC voltage range of 8V to 36V.

EDATEC offers DIN Rail and Wall mount options for the system with the enclosure. The eMMC models ship with a custom version of the 32-bit version of the Raspberry Pi OS (Desktop), but the company also offers Raspberry Pi OS 32-bit/64-bit Desktop or Lite version. Alternatively, you can also install the stock Raspberry Pi OS image and manually installed the BSP with apt in order to support specific features:

You’ll find further technical details on the documentation website.

It looks like the CM4 Industrial has been around for a few years since the product page’s URL is dated from 2019, but there have been several revisions of the board, and currently, only V1.3 and V1.4 should be for sale. Just like with the earlier EDATEC boards, there are many variants due to the combination of options, and the diagram below explains how to decode a specific part number.

The EDATEC CM4 Industrial carrier board (CM4IND) can be purchased on Aliexpress for $93.30 without any module, and $136.28 with the CM4IND and a Raspberry Pi CM4 1GB/8GB module. The 4G module is offered as an option for $40.73. The Aliexpress seller does not use the nomenclature above, and all photos are for the V1.1 board, so you may want to have a chat with the seller to make sure they’ll send the latest V1.4 board, and not some old stock.
