Have you had a look at the NanoPi NEO at $8. I'm considering it for a=20 project under way using the DietPi OS (stripped down/minimalist=20 raspbian/debian) to store pictures from an Ethernet camera and then=20 serve them to a client on request through a web app. It has a quad core H3 processor and a very small form factor. Processing=20 power is in the range between pi2 and pi3, so way more than the zero. =20 Good for headless applications as there is no HDMI and fairly power=20 efficient. The big gotcha is the shipping price, which doubles the=20 cost. If you need to run it hard it requires a heat sink or it will=20 throttle.=20 http://www.friendlyarm.com/index.php?route=3Dproduct/product&product_id=3D1= 32 Gordon Williams On 16-11-21 08:37 AM, Denny Esterline wrote: >>> The limit one prevents me from buying enough to spread the shipping out >>> over enough to bring it down to what I consider reasonable. >> What limit would make it reasonable?
