What is Raspberry Pi
For about only 35$ you can buy a complete ARM compatible PC.
The Raspberry Pi (short: RPi or RasPi) is an ultra-low-cost ($25-$35) credit-card sized Linux computer.
The Raspberry Pi measures 85.60mm x 56mm x 21mm, with a little overlap for the SD card. It weighs 45g.
Graphics capabilities are roughly equivalent to Xbox 1 level of performance.
Overall real world performance is something like an old 300MHz Pentium 2, with kind of better graphics.
The device is powered by 5v micro USB.
Raspberry Pi emulator
You can use qemu emulator that works on Linux and Windows to run and test almost any Raspberry compatible distribution. The emulator will take care of abstracting the necessary ARM underlying hardware when the system is turned on. For detailed instruction we can use Google or follow one of these links:
- windows qemu
- Linux qemu
