Netduino is an open-source electronics platform using the .NET Micro Framework. Featuring a 32-bit AT91SAM7X512 microcontroller and a rich development environment, it is suitable for engineers and hobbyists alike. With Netduino, the world of microcontroller programming is at your fingertips. Netduino is designed to enable both personal projects and sophisticated commercial endeavors. This Netduino Mini shares the same form factor as the popular BASIC Stamp 2 modules. Netduino Mini Features Input. Output. — Create interfaces with switches, sensors, LEDs, serial devices, and more. Netduino combines 16 GPIOs with SPI, I2C, UART, 4 PWM and 4 ADC channels. Code. Debug. Repeat. — .NET Micro Framework combines the ease of high-level coding and the features of microcontrollers. Enjoy event-based programming, multi-threading, line-by-line debugging, breakpoints and more. Design files included. — Netduino is an open-source electronics platform. Design files and source code are included. Learn from the designs. Remix. Enjoy the freedom of open source. You can program Netduino Mini via its RS232 port (pins 1 and 2) or via its 3.3V TTL UART port (pins 11 and 12). By default, Netduino Mini uses the RS232 port for programming/debugging (and the UART is available as a serial port for your code). To program/debug via the 3.3V TTL UART instead, open up a serial connection (using Putty/HyperTerminal/TeraTerm/etc.) to the TTL UART at 115200,N,8,1 and press Escape. Then select the port you’d like to use for program/debug. Netduino Mini Hardware Specifications  - 32-bit Atmel AT91SAM7X512 ARM7 microcontroller, 48 MHz, with 152KB for code storage and 64KB RAM
