Adafruit Raspberry Pi Model A 256MB RAM

The Raspberry Pi is a versatile, credit-card sized computer designed to plug into your TV and keyboard. Powered by a Broadcom BCM2835 SoC, it features an ARM1176JZF-S 700 MHz processor and VideoCore IV GPU, offering a compact computing solution for a myriad of tasks.

Specifications include 256MB RAM and one USB port. It boots via SD card, enabling customizable long-term storage. Compatible with Linux-based operating systems, it mirrors many desktop functions such as spreadsheets and game-playing, while also supporting high-definition video playback.

No built-in real-time clock necessitates a network time server or user input at boot up for timekeeping, though a DS1307 real-time clock can be added through the I2C interface. Supporting various peripherals, its flexibility is matched by robust community support and accessory options from Adafruit.
