The MikroTik KNOT Embedded LTE4 (EC25-EU&KNe) is a compact and powerful LTE gateway specifically designed for industrial IoT and automation projects. Developed for use in confined spaces such as coffee machines, vending machines, smart city infrastructures, and industrial control cabinets, this device offers easy installation with its DIN rail mountable design. Running on RouterOS, it provides LTE Cat4 connectivity along with Bluetooth 5.4 and GNSS support, serving as a versatile data collection and communication hub. Technically equipped with an 800 MHz ARM Cortex-A7 processor, 256 MB RAM, and 512 MB NAND storage, the KNOT Embedded LTE4 includes an LTE Cat4 modem capable of 150 Mbps download and 50 Mbps upload speeds. With 2x2 MIMO support for improved signal quality, the device can be powered via PoE-in (802.3af/at) through its single Gigabit Ethernet port. It can also be powered via USB-C at 5V and operates reliably in harsh temperatures ranging from -40°C to 70°C. With Nano SIM and eSIM support, a 24V-tolerant GPIO header, and an internal Bluetooth antenna, it fully meets industrial requirements. This device caters to a wide range of applications, from smart city sensor networks and industrial automation cabinets to vehicle tracking systems and providing LTE backup connectivity for existing Ethernet devices. It is an ideal solution for system integrators who need to collect data from BLE-based IoT sensors, perform GNSS location tracking, or control remote devices via SMS. Thanks to RouterOS's VPN, firewall, and automation features, it can be used confidently as both a primary gateway and a backup connection.
