MikroTik KNOT Embedded LTE4 Industrial IoT Gateway
The MikroTik KNOT Embedded LTE4 (EC25-EU&KNe) is a tiny, DIN-rail-mountable industrial LTE Cat4 gateway purpose-built for IoT integrators, automation specialists, and smart-city engineers. Originally designed for coffee and vending machine monitoring, it delivers LTE Cat4 connectivity, Bluetooth 5.4 for BLE sensor integration, built-in GNSS/GPS, eSIM support, a sensor-ready GPIO header, and RouterOS v7 — all in a passively cooled, 7W form factor that fits anywhere space is limited but reliability is critical.

The MikroTik KNOT Embedded LTE4 (EC25-EU&KNe) is built for the spaces that most networking hardware cannot reach — automation cabinets, vending machines, kiosks, utility meters, parking sensors, and vehicle tracking systems. It packs LTE Cat4, Bluetooth 5.4, GNSS, GPIO, eSIM, and RouterOS v7 into one of the smallest and most affordable industrial gateways MikroTik has ever made.
Mount it on a DIN rail inside any control panel or cabinet, connect an external antenna via the SMA connector, insert a Nano SIM or activate the embedded eSIM, and it is ready to go. RouterOS provides the full networking stack — VPN tunnels, firewall rules, SMS control and notifications, scripted automation, and remote management — without any additional licensing or subscription cost.
The GPIO header adds a direct path to physical sensors and actuators: digital input, analog input, and open-drain output — all 24V tolerant — enabling simple automation and monitoring logic without an external PLC or microcontroller.
