Does the Arduino Yun have to be powered exactly at 5V?
It is fine. That is only 2% too high. The microcontroller is the ATmega32U4 and it can have 5.5V. The wifi module runs at 3.3V, and it has a voltage regulator. Some voltage is also lost in the cable. ...

Arduino Yun Disk Expander low memory but it looks like my memory is fine
I don't have a YUN or a lot of experience with OpenWRT, so I'm not sure I'm going to be of much help but, I'm guessing the error you're seeing is from this line of the sketch.

Arduino Yun receives UDP packets but prints them with gibberish
You send only 5 or 6 characters "test\r\n". the rest is random memory content.

Sending file from PC to Arduino
You can send a file, byte after byte, using Serial.
On the Arduino side, you parse serial communication and put bytes inside an array. At the end, you reconstruct the file.

Arduino YUN Rev. 2 power supply
For version 1 VIN is connected, through a Schottky diode, to the 5V rail. That means you can only provide, at absolute most, 5V plus a little bit for the diode drop into VIN. The 5V pin can only ...

What's the maximum number of keys in Yun Bridge?
The data is just stored in an array within the Python daemon. The ATMega32U4 just sends commands to set / get the values, so there is no limit imposed by the ATMega side of things.

Arduino Uno and Arduino Yun software. Which version of the IDE works with both best?
The Yun startup was written when the normal IDE didn't support the yun, so you had to use a release candidate of a future version.
Those days are long gone.
Always use the latest version of the IDE.
