Netduino Plus 2

The Netduino Plus 2 is an open-source electronics platform powered by the .NET Micro Framework. Built around an STMicro Cortex-M4 microcontroller running at 168 MHz, it offers a rich development environment for writing embedded applications in C# — making it ideal for developers who prefer .NET over C/C++.

With 384 KB of code storage, 100+ KB RAM, built-in 10 Mbps Ethernet, and Micro SD card support, the Netduino Plus 2 is well equipped for connected projects and data logging.
