ARDUINO YÚN || ARDUINO ETHERNET REV3 WITHOUT POE

Hello ,

My boss gave me a new assignment to make something new. Only this time we decided to use a Arduino.

The problem is i'm not sure wich one to use.
We are trying to make so that a sensor catches a movement , when there is a movement detected we want the arduino to send a multicast network trigger (UDP). When my python script detects a trigger it needs to put something on the screen. I'm using scala digital signage program for that.

The only question i'm asking what would be better to use for this project ,
ARDUINO YÚN OR ARDUINO ETHERNET REV3 WITHOUT POE

I don't have any experience with them but those Yuns are super expensive and people have lots of problems with them. I don't know what kind of availability there is of the Arduino Ethernet. You might be better off to use a regular board with an Ethernet shield or module.
