The fanless Arm Linux IoT gateway supports DIN-rail and wall/VESA mounting, and ships with a Debian-based Linux distribution with built-in Docker support and deployment tools. Compulab also offers a Yocto Project 4.0 BSP with Linux 5.15 and u-boot bootloader for customers wanting to customize the distribution. Additionally, Microsoft Azure IoT and Node-RED IoT frameworks are supported, and OTA updates can be integrated using a pre-configured Mender layer.

Customers preferring to integrate the solution into their own chassis or enclosure can opt for the SBC-IOT-IMX8PLUS single board computer instead.

Compulab IOT-GATE-IMX8PLUS IoT gateway and SBC-IOT-IMX8PLUS board are available now starting at respectively $146 and $124 for volume orders through distributors or direct sales. As usual (for Compulab), you’ll find detailed pricing information per option and volume on the product page. Further details may also be found in the announcement.
