Something more better and power for rfm

[florin.tanasa]

Hi, I found this embedded SMD module
http://www.acmesystems.it/aria
Is very easy to build a linux system with network (eth or wifi), usb, camweb, etc.
Have RTC and consume is very small approx.r 0,5W.
I have in plan to make a base with this for home management.

I don't really see the light here... 
Just get a RaspberryPi...

I see the liberty to build only that is necessary.
In automation is important to use real time kernel with very small consume.
I have this board with sam9g45
http://www.mini-box.com/pico-SAM9G45-X
and I was very impressed how can this work. The difference from sam9g45 and sam9g25 is only lcd.
Look some example at my board with sam9g45 how can work with gentoo
http://www.youtube.com/watch?v=kgrGEQaFH38 and the temp of the board is very ok, have, spi, i2c, rs232 and adc at gpio
Ofcourse is possible to put in raspberry pi  real time kernel

Still not seeing the light ... really ... do yourself a favor and just get a Pi

I have a raspberry pi, pico-sam9g and odroid U2.

The reason I said I didn't really see the point of those boards is because I've also looked into such solutions before the Pi even existed. I mingled with a few boards for a while and all were a royal pain to use. I've even tried Netduino (which is not really comparable in all aspects but still) which was by far the worst. I've not used the BeagleBone yet, reason being that I started with Pi back when BB was still ex$pen$sive, but is probably a really nice board.

The boards you enumerated are all not quite impressive from a feature stand point. Not to mention price.
There are many reasons for choosing a board that can run a real OS for such apps as home automation, the benefits far exceed the disadvantages. Most importantly the users want usability, portability, and out of box features that won't require special compilers and expensive platforms and programmers to use.

The coolest thing back before Pi existed was to hack your much less capable $150 router and load it with a customized open-wrt variant that you might have had to compile specific for that router. What a pain, but it was really cool when it worked. Now with Pi all that nonsense is gone.

I think RaspberryPi really nailed it all around .. and all for ~$40, are you kidding me?

Agreed, when you're talking about the price point, it's hard to argue against the Pi, and you don't need to solder on the components or get shields to do the Ethernet and USB if you're going that route.  Not to mention the strong community support behind it.

The only thing the Pi lacks to make it perfect is an onboard RTC.

Thankfully adding a GPS derived serial clock source is (fairly) trivial, and you get a whole slew of added benefits.
