MikroTik KNOT

IoT Gateway for the most versatile and cost-effective setups

The newest addition to the MikroTik IoT product family – KNOT – is a truly universal device with exceptional connectivity options and protocol support. It is an IoT Gateway that uses Narrow Band and CAT-M technology. Because of the low cost, low bandwidth cellular connection, it is supported by countless mobile operators around the globe. KNOT can monitor onboard GPIOs, convert Modbus protocol to TCP, and even forward Bluetooth packets to TCP/IP network via HTTPS and MQTT.
You can use the KNOT as a TCP bridge from wired Modbus sensors to send readings to a Modbus server. Yes, the KNOT brings wireless connectivity to wired sensors and actuators, such as electricity meters and relays.

It could be used as a backup connection for the Ethernet or as a management channel for your network. NB/CAT-M monthly plan is much cheaper than LTE. Why spend extra money on bandwidth you don’t need? For example, you can manage a KNOT-powered vending machine with temperature and moisture sensors with only a few megabytes per day!

KNOT features so many protocol support and connectivity options: 2.4 GHz wireless, Bluetooth, 2x 100 Mbps Ethernet ports with PoE-in and PoE-out, Micro-USB. Maximum convenience at the lowest cost!

• GPS (GPS, GLONASS, BeiDou, Galileo) - SMA female
• Narrow Band a LTE Cat M1 technologie - SMA female
• Wi-Fi (802.11b/g/n), 300 Mbps, 2x2 MIMO
• 2x 10/100 Mbps (1x PoE IN, 1x PoE out)
• Bluetooth 5.2
• Operating system RouterOS, License level 4
• SIM slot
• RS-485/Modbus and GPIO
• Operating temperature: -40 to +70 °C
• Number of DC inputs: 3 (PoE-in, DC jack, MicroUSB)

How would all this work in real life? Well, let’s imagine a hospital. Lots of expensive assets moving across huge buildings. Tools, equipment, meds, you name it. Everything gets moved around all the time. Usually, hospitals have to spend a lot of resources on inventory checking.
Let’s fix that. Place low-cost Bluetooth tags on all the important items. Add a KNOT device in every storage room. Now the hospital management always knows if the equipment is returned to its place. Why stop there? You can add temperature sensors to medical supplies and use the KNOT to keep track. The possibilities are endless.
