Do ethernet shields need an Arduino Uno / Mega?

Hi,

I am relatively new to Arduino.
I have a question regarding the Ethernet shield W5100.
Can it work alone without an Arduino Uno / Mega?
And how about the Ethernet Shield Nano ENC28J60?

Thank you,
Henrik

Can it work alone without an Arduino Uno / Mega?

For what purpose? The shield is not a standalone microcontroller. It is the microcontroller that is the server or the client. The shield just enables the connection to the network, and the packaging of the requests (client) or responses (server).

And how about the Ethernet Shield Nano ENC28J60?

An even-less-capable piece of hardware.

Hi PaulS,

Thank you for your reply.

You are probably trying to compare it to an ESP8266, which DOES have capability to store some user code and it can run by itself, but so far nobody, as far as I know, has found a way to store user code into the WIZ5100/5500/28J60 IC
