Compulab IOT-LINK is a low-cost, tiny industrial IoT gateway based on NXP i.MX 9352 Arm Cortex-A55/M33 AI SoC with support for Gigabit Ethernet, 4G LTE Cat 1-bis, WiFi 6, Bluetooth 5.4, and Wireless Mesh connectivity.
The fanless gateway also features two RS485 or CAN-FD interfaces and three DI / DO, and as an industrial-grade hardware platform, it takes 12V to 24V DC input, and can operate 24/7 in the -40°C to 80°C temperature range. Target applications include HVAC monitoring, industrial predictive maintenance, energy storage, EV charging, vehicle telematics and fleet management, and lighting control.

The IOT-LINK supports DIN-rail and wall mounting. The company mentions SBC (SBC-IOT-IMX93) and System-on-Module versions are available, so I’d assume it’s based on Compulab’s MCM-iMX93 system-on-module introduced about a year ago.
Compulab offers an open-source software stack with Debian Linux and Yocto BSPs with Linux 6.6, support for Docker, MS Azure IoT and Node-RED, OTA updates with Mender, Modbus RTU, Modbus TCP, and MQTT connectivity, and support for the BalenaOS platform.
Compulab will soon offer the IOT-LINK industrial IoT gateway on its online store with various options. Pricing starts at $89 for volume orders, the company offers a 5-year warranty, and promises a 15-year availability for the gateway. Additional information may be found on the product page.
