Mikrotik KNOT IoT Gateway TCP Bridge LR8 Kit - RB924iR-2nD-BT5+BG77+R11e-LR8

The Mikrotik KNOT LR8 kit is an out-of-the-box IoT gateway solution for LoRa technology that boasts both Narrow Band and CAT-M interfaces. The KNOT LR8 is supported by most mobile operators around the world thanks to its low bandwidth cellular connection, and is pre-installed with a UDP packet forwarder for use with any private or public LoRa server.

Support is also available for up to 8 different channels, Listen Before Talk (LBT), and spectral scan features which add to the versatility of the KNOT LR8. The LoRa 8 Kit can act as a low-cost management channel or backup connection on ethernet for your network as NB/CAT-M plans are often cheaper than LTE. High bandwith LTE contracts are not necessary as you can manage low-use, KNOT-powered devices for just a few megabytes per day.

The KNOT LR8 features a wide range of connectivity options to suit your needs; 2.4GHz WiFi, Bluetooth, LoRa, 2x 10/100 ethernet ports (PoE-in and PoE-out), and Micro-USB. The bluetooth interface can be used in asset-tracking scenarios and the KNOT supports any BLE tag that sends advertisement data (e.g. iBeacon, Eddystone, etc). Powerful filters ensure that only the relevant packets are forwarded and the rest are ignored.

The onboard GPIOs allow the LR8 kit to interact with analogue sensors, a single onboard computer or other custom electronics. There is also a DIN rail mount included with the kit that allows for easy integration with a wide variety of setups.
