Arduino and Raspberry Pi compliant STM32 Embedded Pi board

The Embedded Pi, based on the STM32F103 MCU, is a triple-play platform for Raspberry Pi, Arduino™ and the STM32 MCU family. Blending all three communities together, the Embedded Pi helps you to get the most out of each platform. The Embedded Pi can operate in 3 modes: Standalone, ST-Adapter and Raspberry Pi.

In Standalone mode the Embedded Pi acts as a base platform, the STM32F103 controls the Arduino™ shields directly.

In ST-Adapter mode the Embedded Pi controls the Arduino™ shields, and the Raspberry Pi acts as the GUI or command line console that send commands and data to, and receives data from, the Embedded Pi.

In Raspberry Pi mode the Embedded Pi acts as a hardware connection bridge between the Raspberry Pi and Arduino™ shields.
