Raspberry Pi Model A Rev 1 Development Board overview
The Raspberry Pi Model A Rev 1 is a single-board computer developed in the UK by the Raspberry Pi Foundation. The Raspberry Pi Model A Rev 1 is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for a wide array of applications, like spreadsheets, word-processing and games.
The design of the Raspberry Pi Model A Rev 1 is based around a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 256 Megabytes of RAM. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage. This board is intended to run Linux kernel based operating systems.
