True. But I was thinking about people who want to tinker on an existing Arduino and who are not very hardware savvy (like me): having the specs of a shield they could build or get built for tinkering could be useful.<div><br></div><div>Bruno<br><br>On Tue, 9 Apr, 2013 at 5:53 PM, Stuart Poulton <stuart@poulton.org.uk> wrote:<br>

Actually for the cost of producing a shield, you can include the space for the ATMEGA328P. An arduino is an expensive thing to dedicate to a task.

Yes, I think that that's a decent goal, so that of nothing else people can run all or part of their systems actually on an unmodified Arduino for example. The biggest issue there is likely to be level shifting for (for example) the RFM23 that would not enjoy 5V.

<blockquote> Hi all,
The guy from <a href="http://openhomeautomation.net/">http://openhomeautomation.net/</a> has started a series of videos on how to design your own Arduino shield, taking a wather shield as an example: <a href="http://www.youtube.com/watch?v=_NjZxK3acMs">http://www.youtube.com/watch?v=_NjZxK3acMs</a>. So maybe we could consider one of those as part of the Arduino stack? And even if we end up with more compact designs, thinking of it from the point of view of designing a shield would help gel what pins to use for what. In particular, one of the good points he has in the video is that you'd want a custom shield to be compatible with other standard shields such as the Ethernet or the Wi-Fi one so that they can work together.
Cheers,
Bruno
