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.
