Novice Desicion Help Request

Projects General Guidance
1

Hi all,

I am novice to Arduino, but have some experience in electronics per se and used Atmel Boards (specifically the Net IO's) as well (electronic side as well as programming side).

Now, looking into Arduino as an alternative (because there are some nice shields for my usecases) and would appreciate some desicion help on which board to start with.

Here is my usecase:

  • Domotic / Home automation / Internet of Things products

Here are my requirements (in order of significance top-down):

  • as tiny as possible as I look into Domotic apps where the whole thing shall disappear "in walls"
  • LAN-based board (PoE not needed but should be possibloe to enhance, either by enough space around the RJ45 or prepared)
  • option to use "similar layout" with wireless if needed ( I am a cable believer and WiFi distruster )
  • as many as possible I/O's brought to connectors for use but at least 4 in's and 4 out's (preferred 8 each)
  • competitive priceing

Thanks for any suggestions in advance!

Well considering the UNO has 20 in/out pins It sounds like it should work. If you need something smaller the micro should suffice as well. As for ethernet, look for something W5100 based like the ethernet shield for the UNO or one of the other W5100 boards available on ebay.
