Dear ARM fedora contributors,
I am looking for cheap arm single board computer for outdoor use. I am afraid of damages in low temperature (-10 deg C).
Additionally I want to connect some i2c/spi sensors to it. I prefer fedora. Currently, I have proof of concept device using Raspberry PI. It does meteo station (wind speed / direction / temperature/ ..), adsb receiver, and camera.
Can you recommend me some devices?
regards,

You'd need some sort of industrial board with appropriate ratings. The problem with that is they also tend to be expensive.
This one is basically similar in spec to the beaglebone and has -40℃ to +85 ℃ http://www.cnx-software.com/2014/07/04/low-cost-industrial-board-linux-wince...
There's likely a number of other ones based on the TI am33xx and they should be straight forward enough to support Fedora with device tree bits.

I'd differ from Peter's opinion and say instead you should go for something very cheap, on the basis that you can easily replace it if it breaks. A10 OLinuXino LIME (about $30) has several GPIO connectors. It is supported by the Fedora AllWinner Remix, and I think by the main Fedora starting in Fedora 21(?)

You seem to have got something working already, but out of interest did you consider a 1-wire weather station, and then just connecting that to an ordinary computer which can be located far away and inside in the warmth?

Thanks. The Forlink 335x device is almost exactly what I was looking for. I have also one AM335x Sitara for testing, so it will be easy for me to move there.

I consider Forlink as cheap. I think, I can can go for something more expansive than this one. I would like to have more memory.

Thanks. I have very good experience with allwinner a10. It is one of options. We plan up to 20 devices, so I want to decrease maintenance costs.

I am aware of that option. Also, I was about to buy professional weather station, but it cost is ~600 USD and I need to buy additional computer anyway. I was looking around on other projects [1, 2], but finally I decided to create something new. We can discuss and explore other ways how to get such device, but I don't want to go to much into offtopic in this mailing list.
