It's always exciting with the Raspberry Pi Foundation launches a new board, and we know that you're bursting with questions about the all-new Pi Zero. We certainly were.

So here are our top five questions about the Pi Zero that we're anticipating you'll have, along with their answers, of course.

1) What are the technical specifications of the Raspberry Pi Zero?

- CPU: Broadcom BCM2835, can be overclocked up to 1GHz.
- RAM: 512MB on board.
- Power: 5V, supplied via micro USB connector, drawing160mA (even when connected to an HD display).
- Dimensions: 65mm x 30mm x 5mm
- Storage: MicroSD card.
- Video & Audio: 1080P HD video output. Audio output via mini-HDMI connector.
- Operating System: Linux, installed via NOOBS.

2) Where can I buy a Raspberry Pi Zero?

- The new Raspberry Pi Zero is available to order from Thursday, 26th November. Initial stocks are extremely limited, with small pockets of availability in the US and UK. Unless you're one of the lucky few to get your hands on one of the first batch, the next deliveries are due towards the end of December.
- You'll be able to order the new Pi Zero in the majority of countries as more stock becomes available.

3) Does it still run Linux?

- Yes, it does indeed. You install it the same way as always:
  - Download NOOBS and unzip it to a microSD card; connect the Pi Zero to a monitor, USB hub, keyboard and mouse; power it up and follow the on-screen prompts to install the Linux build of your choice.
  - element14 is offering a Pi Zero package that includes a NOOBS microSD card to make your installation quicker and easier.

4) What's the difference between the Raspberry Pi 2 Model B and the new Pi Zero?

- The Pi Zero uses the single-core BCM2835 processor with 512MB RAM as used in the Raspberry Pi 1 series, versus the newer, faster BCM2836 quad-core processor on the latest high performance Raspberry Pi 2.
- To save space the following products have been replaced with alternative solutions or removed completely:
  - 4 USB ports and Ethernet port have been replaced with one Micro USB data port on the Pi Zero.
  - 40 pin GPIO still contains the same pin out on both boards, but the connector remains unpopulated on the Pi Zero.
  - The full size HDMI port on the Raspberry Pi 2 has now been replaced with a Mini HDMI port on the Pi Zero. This requires an adapter to be fitted before connecting the Pi Zero to your TV. The Pi Zero still supports full HD 1080P output.
  - The camera and display interfaces have been removed as well as the 4-pole stereo and composite video port.

5) Why did the Raspberry Pi Foundation create the Pi Zero?

- The Pi Zero follows the same philosophy that gave birth to the Raspberry Pi platform in the first place; low cost computing for everyone. The Pi Zero complements the other models in the Raspberry Pi family by providing an entry-level model with stripped down components to target users with specific solutions in mind.

- Is it the same as the other Raspberry Pis? Yes and no. It's still a fully functioning Linux-based computer with 1080P video output, but it's also much more closely related to the small, efficient, single-purpose world of IoT.
