Ethernet
Ethernet Network Module
- Overview
- Commands
- On-Module Code
Ethernet connectivity module for network communications. This module does not have SSL/TLS support, and therefore does not allow for secure connections. It works great in local networks and controlled internet connections, but will not work with AWS, for example.

Peek under the hood
The script below is this module's driver — it teaches the hardware how to respond to the commands listed above. It ships pre-loaded from the factory; most users never need to open it.

Code that runs directly on this module's MCU. See On-Module Code for an overview.
- Script
- Arduino IDE
This example runs using the default DUELink Internal Engine using its Scripting Language, and it expects the module's driver to be loaded first, see the Commands Tab.
