## Long description

MikroTik KNOT LR8G is a compact gateway/controller for IoT deployments and network management. It is built around a QCA9531 650 MHz processor with 64 MB internal memory, provides dual 100 Mbit/s RJ-45 Ethernet ports, single-band 2.4 GHz Wi‑Fi (IEEE 802.11b/g/n) with up to 1.5 dBi antenna gain, an RS-485 serial interface and NanoSIM support. The device comes in an IP20 enclosure and is intended for use as a local gateway, controller or connectivity hub in small sites and infrastructure-light locations.
Advantages
The KNOT LR8G combines multiple wired and wireless interfaces in a compact housing, enabling straightforward deployment where space and power are limited. Its 2.4 GHz Wi‑Fi and 100 Mbit/s Ethernet ports allow reliable local connectivity, while the RS-485 interface supports integration with serial sensors and controllers. NanoSIM support enables mobile data links when fixed networks are not available. The white, low-profile enclosure and modest power consumption make the unit suitable for indoor industrial or commercial installations.
Suitable for
Industrial monitoring and remote telemetry
Remote device control and serial equipment integration via RS-485
Small-site network gateway for sensors and local Wi‑Fi access
Temporary or mobile installations requiring cellular fallback
