<p><b>Netduino</b> was an <a href="Open-source" class="mw-redirect" title="Open-source">open-source</a> electronics prototyping platform based on the <a href=".NET_Micro_Framework" title=".NET Micro Framework">.NET Micro Framework</a>.

The Netduino <a href="Printed_circuit_board" title="Printed circuit board">boards</a> (except the discontinued Mini and Go models) are designed to be pin-compatible with most <a href="Arduino" title="Arduino">Arduino</a> shields.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> Applications can be built on Windows (with Visual Studio), or on Mac OS (with Xamarin Studio). 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.

<div class="mw-heading mw-heading2"><h2 id="Development">Development</h2></div>

<p>Netduino was invented by Chris Walker, founder of Secret Labs.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>

</p><p>The platform was actively supported by Wilderness Labs and had an active open source community.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> Some time in 2020 Wilderness Labs discontinued Netduino and completely superseded it by Meadow, an STM32F7-based microcontroller board with .NET Standard.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup>

</p>

<div class="mw-heading mw-heading2"><h2 id="Hardware">Hardware</h2></div>

<p>The Netduino family is based on the Cortex-M Micro Processor running the .NET Micro Framework (NETMF) v4.3.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> 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).<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup>

</p><p>The Netduino family consists of the Netduino 3, Netduino 2, and the original Netduino 1 lines. The original Netduino (1st generation) and Netduino Mini (also 1st generation), have been replaced by the much more powerful Netduino 2 and 3 lines.

</p>

<div class="mw-heading mw-heading3"><h3 id="Netduino_3">Netduino 3</h3></div>

<p>The Netduino 3 is based on a Cortex-M4 microcontroller running at 168 MHz with 384 KB of flash storage and 164 KB of RAM.

</p><p>Netduino 3 is offered in 3 different models, the N3 base model, N3 Ethernet model, and the N3 WiFi model; which vary by their internet connectivity mode and their code/flash storage size. All N3 models support persistent storage with SD cards up to 2GB. Both the Ethernet and WiFi models have a Micro SD slot built in to the board. The base model can use SD cards via most Arduino SD Card add-on shields.

</p><p>The N3 technical specifications are as follows:

<div class="mw-heading mw-heading4"><h4 id="Netduino_1">Netduino 1</h4></div>

<p>The original Netduino was based on an <a href="Atmel" title="Atmel">Atmel</a> AT91SAM7X processor running at 48 MHz.

</p>

<div class="mw-heading mw-heading4"><h4 id="Netduino_Plus">Netduino Plus</h4></div>

<p>The Netduino Plus added an onboard <a href="Ethernet" title="Ethernet">Ethernet</a> port and a <a href="MicroSD" class="mw-redirect" title="MicroSD">microSD</a> card reader.<sup id="cite_ref-getting_9-0" class="reference"><a href="#cite_note-getting-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup>

<p>The Netduino mini was a smaller breadboard mountable Netduino in a DIP package.<sup id="cite_ref-getting_9-1" class="reference"><a href="#cite_note-getting-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup>

</p>

<div class="mw-heading mw-heading4"><h4 id="Netduino_Go">Netduino Go</h4></div>

<p>With Netduino Go, all the peripherals were virtualized, with 8 gobus ports replacing the Arduino headers. Additional modules could be added through these ports, and each module had a small microchip which works together with the mainboard.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup>
