In my last article I collected 7 reasons why you should buy a Raspberry Pi.
Now I want to introdruce the available Raspberry Pi models and what you need to start.
All Raspberry Pi models run with Linux e.g. Raspbian (Debian for Raspberry) or Raspbmc (Media-Center). With the new Raspberry Pi 3 you even can run Windows 10.

Accessory
To operate with the Raspberry Pi you need a micro USB cable with power adapter, a SD or a micro SD card and a case.
There are a lot of different cases available in different online shops.
If yout want to use an older Raspberry model like the Raspberry Pi 2 model B and you need WiFi, there are many WiFi USB adapters available.
If you want to overclock your Raspberry then you should use passive cooling elements.
There are also a SSD storage, tiny fans, UPS and extension boards available.
Last but not least there is a huge sortiment of sensors (e.g. temperature sensor, humity sensor, infrared sensor, ultrasonic sensor, radio-controlled clock), which you can connect with the GPIO pins.
Beginners who are not sure if the accessory is suitable for thei board they want to buy, should consider to buy a starter pack. These starter packs mostly contain the power supply, a SD card, a case and the single-board computer.
I hope you got an overview about the different Raspberry Pi models.
Stay tuned and follow me for more articles, DIY guides and interesting projects about the Raspberry PI.
