Embedded Pi board connects Raspberry Pi, Arduino and 32bit ARM mcu

element 14 has launched Embedded Pi, which it says is a low cost 'triple play' platform that blends the Raspberry Pi, Arduino and 32bit embedded ARM communities.

The device, which has been designed around STMicroelectronics' STM32F103 mcu, can operate as a bridge between Raspberry Pi and Arduino shields and as a Cortex-M3 evaluation board.

The board's functionality can be selected by changing the jumper settings. In STM32/standalone mode, the Embedded Pi works as a base platform, with the STM32 controlling Arduino shields without the use of Raspberry Pi. In ST adaptor mode, the Embedded Pi controls the Arduino shields, while the Raspberry Pi works as the GUI or command line console.

This mode takes advantage of the STM32's nested vectored interrupt controller. Finally, the device can work in Raspberry Pi mode, acting as a hardware connection bridge between Raspberry Pi and Arduino shields.

David Shen, Premier Farnell's chief technology officer, said: "With Embedded Pi, we have developed a truly flexible hardware and software development platform that makes it quick and easy for developers to bridge between the popular worlds of Raspberry Pi, Arduino and ARM Cortex-M series mcus."

The STM32F103 mcu, which operates at 72MHz, has 128kbyte of flash, 20kbyte of ram, plus USB and CAN interfaces and a PWM motor control timer.
