With the rpi-b I get that for around $50, power, case, cabling and sd card. This one has ethernet, and they really run reliably and well. >I have to say that what a Pi does well, it does very well, but its got a >lot of stuff you don't need or want for a basic embedded app, and lacks >a lot of stuff you actually do want, like ethernet hardware. > >Its surprising how little of an OS you need to even drive a multitasking >app on a simple processor. > >PIC style chips are designed to do what you seem to be wanting - accept >lots of input data, chew it a bit and spit it out via ethernet, usb or WHY. No, I want a rather full computer near the observation point, one that can run autonomously in prinicple forever (in case there are issues with management or connectivity) but can network reasonably well. This networking is pretty basic though. So the question remains, is there an IP driver for some of the builtin stuff on the rpi0; except running ppp over the serial interface. -- mrr
