LOL, I have stolen these out of old electronics I have gotten at thrift stores in the past.

Hook a wok to the output shaft. Heat up the oil internally and cycle into the wok. This would be the ultimate in stir fry.

Oh my gosh this is a cool chip. It has so many uses I could abuse it with. $20 for a nice nearly 100Mhz processor! Wow!
Ooh, i just had an evil thought. Teensy 3.1 combined with the wifi processor of the Yun. That would be truly diabolical.

Please provide a RS422 version with jumpers to enable the Rx/Tx pins so those can be wired to whatever pins you choose to use as the UART.
Oh, and both RS485 and RS422 require a common ground reference. I used to think they did not, but upon further reading I found it is needed. So providing a ground terminal would be a good thing even if you don’t make a RS422 version.

I am using this board with an RS485 system. It would be really nice if CTS could be tied to a resistor to pull it low and have it connected to a digital output line like PB0. That way the CTS could be used as a control line to control an RS485 transceiver. The resistor makes it so the change does not affect users of the board that might rely on CTS being always low.

Yeah, I was dismayed at this too. I went and picked up a USB micro cable that came with a vehicle 12V to 5V dc to dc converter. Repacked the converter to connect to wires to run off of 12V. Shortened the USB micro cable to a few inches and mounted everything in my chassis. Not perfect, not pretty. Runs well enough. The brand is “Just Wireless Dual USB Car Phone Charger”. It comes with cable to charger adapter. $20 at Walmart.
I am guessing there will be more than one Yun shield for power. Are you using the Wifi programming of the 32u4? The Yun supports programming the 32u4 over wifi. Which makes the cable not needed for me. YMMV.
An hour of engineering time dwarfs the cost of both. So an integrated solution can give you more time to actually solve the problem you intended to solve. The Pi is very capable as is the Yun. If I needed a user interface that connects to an HDMI monitor the Pi is a shoe in. For an embedded wifi capable robot I would reach for the Yun. It depends upon application and needs. Cost is not a factor in some cases. In my case time was way more important than device costs.
Now that I have some time on the Yun I think paying the extra for the integration is well worth it. Even if a Pi could do the same task equally well.
Okay, I rarely get impressed by new boards. I was not impressed with the Due for my needs as the 5V support was an issue. So for certain projects I used the Uno32. Plenty of speed for my app. Now I needed a more generic set of tools for a sensor platform I am building. I wanted Linux and generic 5V IO. So I ordered this board. Wow! Not only are they nicely integrated on board they are nicely integrated in software. This combination is a serious win for my engineering needs. All I need to provide is power to platform and everything else goes over wifi. There is a serious focus on using Python internally and web technologies. Both of these are used a lot in our company.
So if you need a mobile platform for sensors this is a good piece of that system. I used the Yun combined with the Rover (https://www.sparkfun.com/products/10336) and it driver board (https://www.sparkfun.com/products/11593). I am using a couple of the 9 DOF boards for some inertial sensor testing. Putting these together has been relatively simplistic and mainly just deciphering datasheets. The Yun has been the least of the learning curve. That is how you know a device is designed well. You spend little time making it work.

The Martha Stewart that ADMITS she is a crappy cook…well…a not so sober one.
I must not get the humor as this was somewhat painful to watch. I am all for beer at work though…
No public wish lists :(
