The Netduino Plus 2 is a 32bit microcontroller board with SD Card and Ethernet support running the .Net Micro Framework so you can do embedded development with C# and Visual Studio. Enjoy proper debugging and managed code while developing electronics based projects
Netduino Plus 2 looks like an Arduino Uno but on the inside it is a 32bit Cortex-M3 microcontroller from STmicro. It runs the .Net Micro framework allowing you to be super productive writing C# in Visual Studio. Because the Netduino Plus 2 has the same form factor and pin assignments as the Uno it works with Arduino R3 shields.
But there's more. Running at 168MHz the Netduino Plus 2 has 384KB of code space and 100KB of RAM, 4 x UART, 6 x PWM, I2C, 12-bit ADC and DAC. Developers can compile their own firmware using GCC and debug both native and managed code at the same time via the 10-pin MiniJTAG header.
And, there's SD Card support and Ethernet too.
You even get a micro-B USB cable.
