Adafruit Netduino Plus 2 (.NET-programmable microcontroller)

Netduino Plus 2 is an advanced open-source electronics platform harnessing the .NET Micro Framework, designed for seamless integration and robust performance. Equipped with a high-speed 168MHz 32-bit microcontroller, it's engineered for maximum efficiency and creativity.

Enjoy Ethernet with a ready-to-use TCP/IP stack, ideal for network-enabled projects straight out of the box. The microSD card slot offers ample file storage capability, ensuring projects are scalable and easily managed.

Boasting quadruple speed and significantly increased code space over its predecessor, it provides: four serial ports, six PWM channels, and a 12-bit ADC for precise analog-to-digital conversions. Code-driven power headers and 25mA pin output ensure dynamic LED control, all while maintaining compatibility with Arduino "R3" shields due to its 5V digital I/O tolerance.

The built-to-last design is future-proof, enhanced by an adaptable 10-pin MiniJTAG header for versatile firmware development and debugging using GCC. The NETMF firmware integrates OneWire and Time Server, streamlining complex tasks.

Multithreading, event-based programming, and efficient debugging add layers of convenience while developing. Comprehensive tutorials and open source design files encourage customization and productivity. Whether running on Windows or using Mono for Linux and Mac, development remains flexible and versatile.
