Raspberry Pi: a $25 computer on a stick
May 9, 2011
The first version is about the size of a USB key, and is designed to plug into a TV or be combined with a touch screen for a low cost tablet. The expected price is $25 for a fully configured system.
Raspberry Pi’s mission recalls other projects that have attempted to make low-cost computers available to kids, like the One Laptop per Child (OLPC) initiative’s dream of $100 Internet-ready laptops worldwide, or a $35 tablet from India. OLPC has had some notable successes in places like Uruguay, but has run into problems delivering on its low-cost promises — a challenge Raspberry Pi will also face, and with even fewer resources.
The computer is essentially an ARM processor, USB port, and HDMI connection. Connect it to a keyboard and a television or monitor and you have a fully functional Linux system.
Here’s the provisional specification:
- 700MHz ARM11
- 128MB of SDRAM
- OpenGL ES 2.0
- 1080p30 H.264 high-profile decode
- Composite and HDMI video output
- USB 2.0
- SD/MMC/SDIO memory card slot
- General-purpose I/O
- Open software (Ubuntu, Iceweasel, KOffice, Python)
