Questions about the Yun Wifi Shield for the Arduino Uno

I'm thinking of purchasing this Yun shield to use with my Arduino Uno:

My question is .. will I need to provide a separate power source just for the shield? Or will the USB cable that I have connected to the Uno pass through to the Yun shield and provide adequate power to it?

Thanks,

Do you realize that it runs Linux? If you just want to add WiFi to your project, it's complete overkill, and it will be much more complicated than an ESP8266 for example.

To those who are also looking for an answer to my question … here you go:

The short answer is … the USB power source is NOT adequate enough to power both the Uno and the Wifi shield. You need to use a wall wart AC power adapter.
