Raspberry Pi Model A

This page is dedicated to the Italian designed and manufactured single board microcomputer. The project is based on a family of microcontroller board designs manufactured primarily by SmartProjects in Italy,^[2] and also by several other vendors, using various 8-bit Atmel AVR microcontrollers or 32-bit Atmel ARM processors. These systems provide sets of digital and analog I/O pins that can be interfaced to various expansion boards (so-called shields) and other circuits. The boards feature serial communications interfaces, including USB on some models, for loading programs from personal computers. For programming the microcontrollers, the Arduino platform provides an integrated development environment (IDE) based on the Processing project, which includes support for C and C++ programming languages.
