ΑΝΑΛΩΣΙΜΑ

Industrial LTE/BLE/GNSS connectivity that fits anywhere. Originally designed for coffee and vending machines – perfect for all kinds of industrial automation.

KNOT Embedded LTE4 is a tiny but powerful industrial LTE gateway designed for integrators, automation specialists, and IoT system builders. It fits into tight spaces, mounts directly on a DIN rail, and delivers reliable LTE Cat4 connectivity with Bluetooth and GNSS support.

Use it as a primary gateway, a backup link, or an IoT data collection node – everything is powered by RouterOS for maximum flexibility.

Sensor-ready GPIO header
For simple automation and monitoring (Digital input/Analog Input/OD output). All pins are 24V tolerant.

Powered by RouterOS
Full networking stack, VPNs, firewall, SMS control and notifications, automation, remote management, and so much more!

Whether you’re building a new system or adding LTE to an existing installation, KNOT Embedded LTE4 adapts easily. It’s easy to integrate, easy to deploy, and built to perform in harsh environments – from smart city deployments to industrial automation and mobile tracking.
