Netduino Plus 2

Netduino is an open source electronics platform using the .NET Micro Framework. Featuring a 32-bit microcontroller and a rich development environment. Suitable for engineers and hobbyists alike. Input/Output. Interface with switches, sensors, LEDs, serial devices, and more. Netduino offers 20 GPIOs combined with SPI, I2C, 2 UARTs (1 RTS/CTS), 4 PWM channels and 6 ADC channels. 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. Very expandable. 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. Design files included. Netduino is an open source electronics platform. All design files and source code are included. Learn from the designs. Remix. Enjoy the freedom of open source.

Netduino Plus 2 is the new Netduino Plus.It has four times the speed (168MHz), six times the code space (384KB), and twice the available RAM (100KB+) of Netduino Plus 1. They've also given it a whole series of rich new features like four serial ports, six PWM channels and 12-bit ADC. The 6-pin ICSP header has been swapped out 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.
