The MikroTik KNOT LR9G kit is an IoT gateway that combines a 915 MHz LoRa card, an LTE CAT-M1/NB2 modem, GPS, Bluetooth 5.2 and 2.4 GHz Wi-Fi in one RouterOS v7 device.

It can collect data from Bluetooth tags and LoRa sensors, convert Modbus over RS485 to TCP, monitor GPIOs and forward data over MQTT or HTTPS. GPS and the LTE CAT-M connection work at the same time, and the LTE, GPS and LoRa interfaces have SMA female connectors for external antennas.

This is the 915 MHz (902-928 MHz) version. MikroTik also makes an 868 MHz version, the KNOT LR8G kit.

Key features

  • LoRa gateway card for 902-928 MHz
  • LTE CAT-M1 and NB2 modem with nano-SIM slot
  • Bluetooth 5.2 and 2.4 GHz 802.11b/g/n Wi-Fi (2 chains)
  • 2 x 10/100 Ethernet, PoE-in 802.3af/at and PoE-out on ether2
  • DC jack 12-57 V, PoE-in 18-57 V or 5 V microUSB
  • RS485 port for Modbus
  • Single-core 650 MHz CPU, 64 MB RAM, 128 MB NAND

In the box

  • 24 V 1.2 A power adapter
  • K-47 wall mount set
  • DIN rail mount set
  • USB OTG cable
