- 1 gigabyte of RAM
- 4 USB ports
- 1 HDMI port
- 1 Micro SD Card slot
- 40 GPIO pins
- 1 Ethernet port
- 3.5 mm audio and video jack combined
- Camera interface
- Display interface
- Videocore IV 3D Graphics Core
How Can I Get A Raspberry PI 2?
In reality though you will definitely need the following:
- A powered USB hub
- A USB keyboard
- A USB mouse
- An HDMI cable
- A micro SD Card
- A screen (either a monitor or TV with a HDMI port)
- A USB WIFI dongle
- A power supply
- A Case
- Raspberry PI 2 Model B
- SD Card with NOOBS pre-installed
- A power supply
- A case
- An ethernet cable
- An HDMI cable
An HDMI cable can be bought in most pound shops or supermarkets. If you want to buy it from Amazon it will cost £2.26.
If you want to keep the Raspberry PI next to your router then you can use an ethernet cable but personally I think a WIFI USB dongle is more useful.
It is worth getting the official Raspberry PI WIFI dongle so that you don't end up with driver issues. This one costs £8.
You will need a class 10 Micro SD Card for the Raspberry PI 2. These are more expensive than the class 4 SD cards which are found in most supermarkets but I bought one from Tesco with 16 gigabytes for £4.50 during their Christmas sale.
You can get a blank one on Amazon with 32 gigabytes of space for £6.43. This is blank and you will have to install the operating system yourself but you can read the rest of this guide to find out how. It really isn't very difficult and there is a good reason to do it yourself which I will get to later on.
Generally the Raspberry PI can be powered with a mobile phone charger similar to the ones that come with a Samsung Galaxy phone.
The official Raspberry PI site has recommended power supplies and you can buy one on Amazon for £5.87.
Finally there is the USB keyboard and mouse. On Amazon you can shop around and get them for as little as £8.91.
The final total therefore for everything you need is £57.46.
It is worth noting that whilst this puts the cost of buying a Raspberry PI in the initial stages more expensive than the £30 often touted you will only buy the additional items once. If you buy a second PI at a later stage because for whatever reason it breaks or because a newer model is released you won't need to buy the additional extras again.
A case can be bought for as little as £6.29 but you can again shop around and find one that you like.
The power from a single power supply will power the Raspberry PI but when you have a WIFI dongle, keyboard and mouse connected there might not be quite enough power to run them all.
For this reason it is worth getting a powered USB hub. If you intend to run the Raspberry PI as a headless server then you might not need the USB hub as the power supply is capable of running the Raspberry PI and a WIFI dongle.
Many of the components listed above can also be bought from the following sites:
