NETduino 3 Ethernet is an open source electronics platform using the .NET Micro Framework, featuring a powerful 32-bit STM32F427VI Cortex-M4 microcontroller running at 168 MHz. This board combines the ease of high-level .NET programming with the raw features of microcontrollers, suitable for both engineers and hobbyists.The NETduino 3 offers almost four times the code storage (1408 KB) and nearly double the RAM (164+ KB) of its predecessor. The Ethernet model also includes MicroSD storage up to 2GB and an integrated Ethernet jack for high-speed IP networking. Compatible with most Arduino shields (some require .NET MF drivers) 1408 KB code storage capacity 164+ KB RAM 6 ADC channels (12-bit resolution) Micro SD storage (up to 2GB) 3 GoBus ports Operating temperature: 0° - 70°C Power input: 7.5-12 VDC or USB powered Power output: 5 VDC and 3.3 VDC regulated Max current: 25 mA In the box: NETduino 3 Ethernet board Four sticky feet 5 cm GoBus cable Dimensions: 80.3mm x 53.3mm x 12.7mm (3.2" x 2.1" x 0.5")Weight: 27.0g (1.0oz)For detailed schematics, datasheets, and community support, visit official documentation and forums.STM32F427VI Datasheet | NETduino 3 Ethernet Schematics | NETduino Community Forums
