If you're looking to build a network-connected device with Arduino Nano is the best solution for you!

PoE (Power over Ethernet) - is a technology that allows you to transfer power and data through a single Ethernet cable. All that is required is to connect a PoE-issuing device to a PoE-powered device via an RJ-45 network connector. Paired with a controller board, this module will allow you to power your project via Ethernet.
