The Raspberry Pi is a credit-card sized computer board that plugs into a TV and a keyboard. It’s a miniature ARM-based PC which can be used for many of the things that a desktop PC does, like spreadsheets, word-processing and games. It also plays High-Definition video.
Here are the specs:
- Broadcom BCM2835 700MHz ARM1176JZFS processor with FPU and Videocore 4 GPU
- GPU provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode
- GPU is capable of 1Gpixel/s, 1.5Gtexel/s or 24GFLOPs with texture filtering and DMA infrastructure
- 256MB RAM
- Boots from SD card, running the Fedora version of Linux
- 10/100 BaseT Ethernet socket
- HDMI socket
- USB 2.0 socket
- RCA video socket
- SD card socket
- Powered from microUSB socket
- 3.5mm audio out jack
- Header footprint for camera connection
- Size: 85.6 x 53.98 x 17mm
There are some challenges to working with one of these devices. You'll need to use a Linux operating system, for one. But unlike Arduino, this is a full blown computer, minus display and keyboard.
The target market for this is education, DIY types, and hackers.
But for me the important thing is we can have a full blown computing device for $35.
When the cost of tablet displays comes down, which they will, I think we'll see sub $100 tablets. And I suspect that will happen in the next 3-5 years.
For markets that can be end to end digital, like education, this is a game changer.
