May 1, 2024 — by Giorgio Mendoza 264 views

Compulab unveils the IOT-DIN-IMX8PLUS which is an advanced industrial IoT gateway equipped with dual GbE ports and GPS connectivity, offering versatility and robust functionality in a compact, modular DIN-rail form factor and fanless design.

The IOT-DIN-IMX8PLUS features Compulab’s UCM-iMX8M-Plus with the NXP i.MX8M Plus SoC, supporting up to 8GB of RAM and 128GB storage. It includes a quad-core ARM Cortex-A53 processor (up to 1.8GHz) and a real-time ARM Cortex-M7 coprocessor (up to 800MHz), along with a 2.3 TOPS NPU and GC7000UL GPU for enhanced graphics processing.

The gateway’s base unit is loaded with essential connectivity options, including a worldwide LTE/4G modem and GNSS for global data communication and positioning. It also features dual Gigabit Ethernet ports and a USB 3.0 for high-speed data transfer. Serial communication interfaces such as isolated RS485 and RS232, along with a CAN bus and digital I/O options (2x DI + 2x DO), enhance its utility in various industrial scenarios.


A key feature of the IOT-DIN-IMX8PLUS is its modularity. The gateway can be expanded with a range of I/O Expansion Modules through Compulab’s proprietary StackLink interface, allowing up to eight modules to be stacked.

This flexibility enables customization to meet specific connectivity demands by adding additional RS485/RS232 ports, digital I/O, analog inputs, and advanced wireless communication options like Wi-Fi 802.11ax and Bluetooth 5.3.

The IOT-DIN-IMX8PLUS supports Debian 12 Linux with Docker, making the deployment of applications straightforward. For users requiring custom configurations, a Yocto-based BSP featuring Linux kernel 6.1 and U-Boot bootloader is available, with OTA updates managed through a pre-configured Mender layer.

The gateway also supports popular IoT frameworks such as Microsoft Azure IoT and Node-RED, broadening its applicability in diverse IoT ecosystems.
