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.
