Picked up this Yun shield, and figured I could use it with my Leonardo or Due (any particular reason I should pick one over the other besides the Due being more powerful?)
First question is on OpenWRT that comes resident on the shield. I read that this comes with an SSH server, but know very little about linux and have just started to get into Ubuntu. I assume openWRT is minimalist by design, but was curious if it could handle something simple like broadcasting a website to people who connect to it over wifi? I'd like it to broadcast some sensor data, and that's pretty much it. I figured if I wanted to do additional data storage, I could use the onboard sd port. Can the Yun shield do all of these things, and are there any good tutorials/examples out there of such a system?
I read the Yun should be used with the DC connection to prevent overheating to the arduino board. I believe I also read that the two boards combined could handle up to 23v. This may solve my issue of connecting peripherial items like multiple fans, temperature monitors, and servos. Does the added voltage capacity provide the opportunity to add things like these directly to the boards rather than using wall warts or a 120v AC to DC inverter?
