 ===== Hardware reference =====
 The table {{ref>esp32sutnodehardware}} lists all hardware components of the SUT's ESP32-S3 node and hardware details such as connectivity, protocols, GPIOs, etc. Please note that some pins overlap because buses such as SPI and I2C are shared among multiple components.\\

You may still access MQTT messaging via the 2nd MQTT Broker bridged, but it requires specific topic organisation as not all topics are forwarded. Refer to the documentation below.</note>
 If you're a SUT student or can access the campus network, you can also use 157.158.56.0/24 addresses.
+Openthread IP6 network with short addressing (up to 65k devices) is bound to the campus network (UDP forwarding, bidirectional) via Openthread BorderRouter. Refer to the diagram below (figure {ref>sutvrelnextgeninfrastructure}) for details.
