Can I connect external antennas to the MikroTik KNOT to improve LTE and GPS signal?
Yes, the device features SMA antenna connectors, allowing you to bypass the internal antennas. This is critical for installations where the gateway is housed inside a metal control cabinet or in remote areas with weak cellular coverage.
Does the EC25-EU&KNe model include an internal SSD for high-capacity data logging?
While the product listing mentions a 512 GB SSD capacity, there is a discrepancy between the internal flash memory and expansion capabilities for this specific embedded model. For a definitive confirmation on storage hardware for your specific batch, please contact our technical support at apsardze24@gmail.com.
How do I power the MikroTik KNOT Embedded LTE4 and is it compatible with industrial 24V systems?
This gateway is highly versatile, supporting power via 802.3af/at PoE (12-57V) or a 5V USB-C port. Its GPIO pins are 24V tolerant, making it perfect for direct integration into industrial automation environments and vending machine systems.
How does the Bluetooth functionality work for IoT asset tracking?
The KNOT acts as a BLE-to-TCP bridge, using Bluetooth 5.1 to scan for nearby asset tags or sensors. It then relays that data via LTE or Ethernet to your cloud platform, making it an ideal node for warehouse tracking and smart city deployments.
Does this MikroTik gateway support eSIM and which mobile networks can I use?
The KNOT Embedded LTE4 features both a physical NanoSIM slot and eSIM support for flexible connectivity. At Apsardze24.lv, we sell the official EU version (EC25-EU), which is fully optimized for all major mobile operators across Latvia, Estonia, and Lithuania.
What is the warranty and repair policy for the MikroTik KNOT EC25-EU&KNe in the Baltics?
Apsardze24.lv provides a 2-Year Warranty for both business and private customers. We manage all service and technical support locally from our center in Riga, ensuring significantly faster turnaround times than international marketplaces.
Is RouterOS v7 included and does it require a monthly subscription?
The device comes with a full RouterOS v7 license, providing professional-grade firewall, VPN, and SMS notification features. Unlike many IoT gateways, there are no recurring software subscription fees required to use the advanced networking capabilities of MikroTik.
