Netduino is an open source electronics platform using the .NET Micro Framework. Featuring a 32-bit microcontroller and a rich development environment, it is suitable for engineers and hobbyists alike.

The Netduino Plus 2 has Ethernet cooked in already! There is a full TCP/IP stack with examples ready to go, and a microSD card slot for storing files

Netduino Plus 2 has four times the speed (168MHz), six times the code space (384KB), and twice the available RAM (100KB+) of Netduino Plus 1.

Features:

• four serial ports
• six PWM channels
• 12-bit ADC
• power headers that turn on and off via code, so you can power on shields when you want to
• pins can drive up to 25mA of current to light LEDs
• Arduino "R3" compatibile to support future shields (in addition to existing shields, thanks to Netduino Plus 2's 5V digital I/O tolerance)
• OneWire and Time Server directly inside the NETMF firmware
• space in flash for future features

This board is built to last, to get even more feature-rich over time.

You might notice that we swapped out the 6-pin ICSP header for a 10-pin MiniJTAG header. The goal is to enable developers to compile their own firmware using GCC--and debug both native and managed code at the same time. If you need the ICSP header for a shield, simply sandwich a MakerShield in the middle: it'll route the ICSP pins for you.

Code! Debug! Repeat!

.NET Micro Framework combines the ease of high-level coding and the raw features of microcontrollers. Enjoy event-based programming, multi-threading, line-by-line debugging, breakpoints and more.

To get a glimpse of how its done, check out the basic 'getting started' guide You can even now use the Netduino on Linux & Mac computer using open source Mono instead of .NET

And its very expandable just like the Arduino!

3rd-party accessories offer pre-built functionality like GPS location, servo control and battery power. Netduino is also pin-compatible with Arduino shields. 3rd-party drivers are required for some Arduino shields.
