Will you be providing arduino pin headers for shields?<br>
It doesn't need to be populated, but it would fast track adding on the functionality listed above. If you do opt for this, don't forget the ISP header. Many shields (like the Ethernet shield) use if for communication.<br>

Agreed, and while I did think something like the Udoo would be beneficial (and it would be), like you said, the routing might become an issue, especially with the Arduino's non-standard header spacing issue, dual USB hubs, and the AXP20*. For those who want to use arduino shields, might, in this case, be better suited to using a cable. I mainly wanted to cater to the SOFTWARE aspect of Arduino. Being able to execute arduino code natively, while not expressly supporting the arduino shields would be the best compromise in my opinion. And to be honest, I've never personally used a genuine arduino w/ shield. It has always been a simple atmegaNNNN running arduino code hooked up to whatever project I was working on.(Granted, I'm not "everyone" and probably the minority in these situations.)</div>
<div><br></div><div>Take this Door Chime Relay I made/hacked up for my 1995 VW Golf a few years back, dead-bug/freewired a bare 32 TQFP to an ICSP header and 7805, superglued the 0402 capacitors to the underside of the chip with magnet wire shards providing the connections. :) It ran a simple arduino MIDI sketch.</div>

<br></div><div>I think if it's possible to offer shield compatibility without making it overly complex, great, but the scope was just to provide GPIO for the new and old hacker to use as they see fit using the Arduino IDE or WinAVR/AVRDude gcc stuff. If I were to use a larger Atmel or STM32F with 30+ GPIO, I might consider it. But I wanted to get away with as small a board possible while still maintaining the connectivity.</div>

The Udoo is all in one ARM PC with Arudino Mega footprint on board.I rather certain this is device that Luke was referring to in another post.<br>

(Although if we use the AXP20XX, I believe it can handle the 3.3v Power requirements on LD0). That's not to mention it's a $7 chip (vs $1.87 or less for the ATMEGA32U4) and 144-LQFP, and would require significant design changes. </span></div>
