Netduino was an open-source electronics prototyping platform based on the .NET Micro Framework.
The Netduino boards (except the discontinued Mini and Go models) are designed to be pin-compatible with most Arduino shields.
The platform is similar in concept to the Arduino platform, but is generally more powerful and instead of writing applications in C/C++ or Wiring (essentially, C++ without header files), applications are written in C#, which brings powerful, high-level language constructs to the toolbox such as threading, event handling, automatic garbage collection, and more.
[3][4] Some time in 2020 Wilderness Labs discontinued Netduino and completely superseded it by Meadow, an STM32F7-based microcontroller board with .NET Standard.
[6] Development can be done on both Windows, with Visual Studio, or with Xamarin Studio on Mac OS X. IO includes 22 General Purpose Input/Output (GPIO) ports, 6 of which support hardware Pulse Width Modulation (PWM) generation, 4 UARTs (serial communication), I2C, and SPI (Serial Peripheral Interface Bus).
