I have been working a project which basically has to be all things to all men - Serial Comms, lots of I/O, Internet access, SD card. We started off with a standard Arduino and Ethernet shield, but this did not have the "buffered" UART - useful Serial comms. We looked at a Chipkit Max32, but whilst it is advertised with Ethernet it requires a second shield the Arduino Ethernet does not work). We also tried out a PIC development board (but I am not an electronic engineer and that made my head hurt too much) We then looked at the Netduino Plus- on the face of it, it has everything - great price, buffered UART - Ethernet, SD Card, plenty of I/O, and it uses - NET MF, as we have lot of .Net code already - we thought we were in business. The prototype was built and I started coding. This is when it started to fall apart - to use my mother's express it was like trying to squeeze a quart into a pint pot (too much into too small a space). I would get parts of it going on their own, merge it together and it would stop working sometimes with obvious memory related errors - sometimes it would just die. It has become very frustrating. So to my question - what should I do? 1. Are there tricks I can use to make the use of memory very efficient so I can use Netduino? 2. Go back to one of the other platforms - if so which one? 3. Try a new platform - which one? 4. Go for a bespoke solution rather than off the shelf components?

Ugh!...It looks as the death would be the only way to solve your problem! I don't know...could you be more specific on your app? I learned that you cannot use the best-practice patterns of a normal PC, because they require lot of resources. You should code much like the C++ way.
Biggest fault of Netduino? It runs by electricity.
