3. Plug the video cable into the screen (TV) and into the Pi.
4. Plug your extras into the Pi (USB WiFi, Ethernet cable, hard drive etc.). This is where
you may really need a USB Hub.
5. Ensure that your USB Hub (if any) and screen are working.
6. Plug the power source into the main socket.
7. With your screen on, plug the other end of the power source into the Pi.
8. The Pi should boot up and display messages on the screen.
It is always recommended to connect the MicroUSB Power to the unit last (while most
connections can be made live, it is best practice to connect items such as displays/h/w pin
connections with the power turned off).
The RPi may take a long time to boot when powered-on for the first time, so be patient!
Prepared Operating System SD Card
As the RPi has no internal storage or built-in operating system it requires an SD-Card that is
set up to boot the RPi.
• You can create your own preloaded card using any suitable SD card you have. Be sure
to backup any existing data on the card.
• Preloaded SD cards will be available from the RPi Shop.
This guide will assume you have a preloaded SD card.
Keyboard & Mouse
Most standard USB keyboards and mice will work with the RPi. Wireless keyboard/mice
should also function, and only require a single USB port for an RF dongle. In order to use a
Bluetooth keyboard or mouse you would need to use a Bluetooth dongle, which again uses a
single port.
Remember that the Model A has a single USB port and the Model B only has two (typically a
keyboard and mouse will use a USB port each).
Display
There are two main connection options for the RPi display, HDMI (high definition)
and Composite (low definition).
• HD TVs and most LCD Monitors can be connected using a full-size 'male' HDMI
cable, and with an inexpensive adaptor if DVI is used. HDMI versions 1.3 and 1.4 are
supported, and a version 1.4 cable is recommended. The RPi outputs audio and video
via HMDI, but does not support HDMI input.
• Older TVs can be connected using Composite (a yellow-to-yellow cable) or via
SCART (using a Composite to SCART adaptor). PAL and NTSC TVs are supported.
When using composite video, audio is available from a 3.5mm (1/8 inch) socket, and
can be sent to your TV, to headphones, or to an amplifier. To send audio your TV,
