The Forlink 335x device is almost exactly what I was looking for.

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. > > Additionally I want to connect some i2c/spi sensors to it.

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.
