Anatomy of a Raspberry Pi

Hi! This is your Raspberry Pi. Click on the different parts to get more information

  1. RCA video out port

    What it does:

    Sends video out of your Raspberry Pi to a TV, where it can be displayed.

    What connects to it?

    A RCA cable to a television or monitor, or to a SCART cable.

    Is it required to get started?

    No. If you use the HDMI port to connect , you won't need to use this.

  2. Audio out port

    What it does:

    Sends sounds and music out of your Raspberry Pi to a speaker, which will play it.

    What connects to it?

    An audio cable that connects to a speaker, TV or stereo system.

    Is it required to get started?

    No. You can use your Raspberry Pi without sound; you just won't be able to hear it make any noises or play music.

  3. USB 2.0 ports

    What it does:

    Delivers data back and forth between the Raspberry Pi and external things (external hard drives, keyboards, mice, CD or DVD drives, etc.)

    What connects to it?

    • A keyboard (with a USB cable)
    • A mouse (with a USB cable)
    • An external hard drive, DVD or CD drive
    • A laptop or desktop (with SPECS), if you are using the USB port for power.
    • A wifi or mifi dongle (explain what those are – and check the wording)
    • A USB hub, which will allow more than two USB devices to be connected to your Raspberry Pi at once. A powered USB hub (with a power cable of its own) will handle more devices than one that just pulls power from the Raspberry Pi.

    Is it required?

    Yes, you will need a keyboard (at least)

    You will need to use a USB cable to your computer as a power source, if you don't have a power supply cable plugged in to the micro

  4. LAN / Ethernet port

    What it does:

    Connects your Raspberry Pi to the Internet via a wired connection.

    What connects to it?

    An ethernet cable, which connects to a router, cable modem or ethernet hub.

    Is it required?

    No. You can start using your Raspberry Pi without connecting it to the Internet. Or you can connect your Raspberry Pi via Wifi (see the USB port section of this guide).

    Obviously though, you won't be able to access Web sites, YouTube, or any other computer on your network until you have either an ethernet connection or a Wifi connection.

  5. HDMI out port

    What it does:

    Connects your Raspberry Pi to a monitor or TV for displaying images.

    What connects to it?

    An HDMI cable, which then connects to a monitor or TV

    Is it required?

    Yes, you must have the Raspberry Pi connected to a display of some sort. This will either be through the HDMI port or the RSA Video Out port

  6. Power port (Micro USB)

    What it does:

    The Micro USB power port delivers power to the Raspberry Pi.

    What connects to it?

    • A power cable sold specifically for Raspberry Pis.
    • A Micro USB phone charger for Blackberries, Androids, etc.

    Is it required?

    Yes, unless your Raspberry Pi is connected to a computer or power source through a USB cable.

  7. RAM

    What it does:

    The Random Access Memory temporarily stores the data your Raspberry Pi is currently working with.

    What connects to it?

    It is soldered directly to the motherboard.

    Is it required?

    Yes. But because it is soldered to the motherboard, you can't take it off.

  8. CPU – Broadcom 700Mz Chip

    What it does:

    The central processing unit it is the brain of your Raspberry Pi. It processes everything the Raspberry Pi is doing.

    What connects to it?

    It is soldered directly to the motherboard.

    Is it required?

    Yes. But because it is soldered to the motherboard, you can't take it off.

  9. GPU

    What it does:

    The graphics processing unit (GPU) creates and prepares images for the monitor or TV screen.

    What connects to it?

    It is soldered directly to the motherboard.

    Is it required?

    Yes. But because it is soldered to the motherboard, you can't take it off.

  10. SD card slot

    What it does:

    It holds a secure digital (SD) card, which is the Raspberry Pi's hard drive. The SD card will store the Raspberry Pi's operating system and software.

    What connects to it?

    An SD card.

    Is it required?

    Yes, you must have an SD card with an operating system that is supported by Raspberry Pis already loaded on it.

  11. GPIO pins

    What it does:

    The general purpose input/output (GPIO) pins can connect the Raspberry Pi to cables for other devices.

    What connects to it?

    Interfaces to external circuit boards.

    Is it required?

    No, you won't need to plug anything into your Raspberry Pi's GPIO pins before you start it.
