+### Ethernet
+
+The Arduino IoT Cloud supports connection via Ethernet on a number of devices.
+
+To connect via Ethernet, you need a [Portenta H7](https://store.arduino.cc/products/portenta-h7) board, in combination with one of the following shields/carriers:
+- [Portenta Vision Shield Ethernet](https://store.arduino.cc/products/arduino-portenta-vision-shield-ethernet)
+- [Portenta Machine Control](https://store.arduino.cc/portenta-machine-control)
+
+To enable communication via Ethernet with the Portenta H7, while configuring your device, you need to select the "Ethernet" option. If your device is already configured as a Wi-Fi device, you need to remove it before configuring it to Ethernet communication.
