MikroTik KNOT RB924i IoT Gateway
€73,09 €89,90 Incl. VAT
The MikroTik KNOT (RB924i-2nD-BT5&BG77) is an IoT gateway with an NB-IoT and CAT-M modem, GPS, Bluetooth 5.2, 2.4 GHz Wi-Fi and two Ethernet ports, running RouterOS v7.
It can monitor its GPIOs, convert Modbus over RS485 to TCP, and forward Bluetooth packets to a TCP/IP network over HTTPS or MQTT. That lets wired sensors such as electricity meters report over a low-bandwidth cellular link. The CAT-M and GPS interfaces have SMA female connectors for external antennas.
