Netduino is an open source electronics platform using the .NET Micro Framework. Featuring a 32-bit microcontroller and a rich development environment, it is suitable for engineers and hobbyists alike. This combines the ease of high-level coding and the raw features of microcontrollers. Enjoy event-based programming, multi-threading, line-by-line debugging, breakpoints and more!

The Netduino 3 has the same 168 MHz (Cortex-M4) processor as the Netduino 2 but almost four times the code storage at 1408 KB and almost double the ram at 164+ KB.  Check out the full specs here and more information about Netduino over at netduino.com
