What is the best board for setting up an SSH protocol to an Arduino? I currently have a project using an Arduino R3, set up across the room from my computer. This has become quite annoying, as every time I want to push something to the Arduino I have to get up and move either the computer or the Arduino to another location, plug it in, and hope my code works the first time, lest I have to repeat the test over and over again. I am trying to set up an SSH server between my Raspberry Pi 2 and computer so I can just push new sketches over SSH, however, I use my Pi 2 for other projects occasionally and want to purchase a second board specifically for this purpose. Is there a good, cheap, board with wifi built in (besides the Pi 3) that I could use for this? Any suggestions?
Sounds like you want an Arduino Yun instead of an Uno.  Or a Dragino Yun Shield that turns your Uno into a Yun.
