What Is the Raspberry Pi Zero?

It’s unlikely that you’ve ever had problems with the dimensions of the already compact Raspberry Pi, but just in case you have a need for an ultra-low-profile minicomputer with very little weight, the amazing chaps at the Raspberry Pi Foundation and its manufacturing partners (PremierFarnell, RS Components and Egoman) have done it again with the tiny Pi Zero.

The latest iteration of the Raspberry Pi is essentially a model A+ but with the ports removed, compressed into a single Micro USB OTG port (the familiar Micro USB power connector remains, the port on the right in the diagram above, supplying a lower-than-previous ~160 mA) and a Mini-HDMI port (RCA composite video is also available via the GPIO, ready for an optional connector to be soldered on). Audio is also sent via Mini-HDMI, but there is a PWM connection on the GPIO for DIY analogue audio out.

At the heart of the Pi Zero is a Broadcom BCM2835 SoC, housing a 1 GHz ARM1176JZF-S single-core CPU, Broadcom VideoCore IV @ 250 MHz GPU (still with HD support), and 512MB SDRAM.

Finally, a MicroSDHC slot is provided, for high storage disks with robust error-connection, while the GPIO is – in a Raspberry Pi first – unpopulated, which means you need to solder your own pins onto the Pi Zero. Among the “missing” components, you’ll find that there is no video input for the Raspberry Pi camera and NoIR camera modules.

Oh, and it’s just $5. Did we mention that?

Resembling a piece of laptop RAM, the only way the Pi Zero could be any smaller is if it was packaged without the USB or HDMI connector. But that would lead to problems with developing projects.

What Do You Get in the Box?

Various kits are available, depending on where you get your Pi Zero from. Following launch of the computer, supplies are very low, thanks to the great success of the device launch. However, various sites currently offer kits for pre-order.

Pimoroni.com list a couple of kits. In the first, you’ll get the Pi Zero, a mini HDMI adaptor and a micro USB OTG cable, which can be connected to a (preferably powered) USB hub, providing connectivity for wireless dongles, keyboard, mouse, external HDD, and any other USB components you need to connect. There’s also a row of GPIO (General Purpose Input/Output) pins for you to manually solder onto the board.

muo-diy-raspizero-kit-pimoroni-big

You will also find a more modest kit, like that shipped on the cover of MagPi magazine, offering the Mini HDMI adaptor, USB OTG cable, GPIO header pins, and little else.

muo-diy-raspizero-kit-pimoroni

Variant kits are also available, depending upon which supplier you use. Along with the USB OTG cable and HDMI adaptor, you might find options including microSD cards and adaptors, a tin or case, rubber feet, and even mains adaptors.

Note that these kits will increase the basic price, depending upon which package you opt for. So while the Pi Zero on its own is only $5 (or £4 in the UK), this might shoot up to $20 or even beyond with the cables, microSD card and GPIO.

Size Comparison

At 65 mm × 30 mm × 5 mm (2.56 in × 1.18 in × 0.20 in), the Raspberry Pi Zero is one hell of a tiny computer.

muo-diy-raspizero-comparison

Less than half the size of the traditional Raspberry Pi, it’s even-more-compact dimensions make it ideal for projects that require a board that can slip into small gaps, as well as one for which weight is a consideration. For example, the Raspberry Pi 2 5 Things Only a Raspberry Pi 2 Can Do 5 Things Only a Raspberry Pi 2 Can Do The latest edition of the pint-sized computer is awesome.

Get Started with the Raspberry Pi Zero

Now you’ve met the Raspberry Pi Zero, it’s time to get it setup, switched on, and start your project. To begin with, you’ll need to install an operating system onto a microSD card. This is done by inserting the card into your computer, usually using an adaptor (although some tablets and notebooks have built in slots for microSD cards), and writing your chosen Raspberry Pi distro to the card.

muo-diy-raspizero-jessie

Currently, the best OS for the Pi Zero is Raspbian Jessie 5 Ways New Raspbian Jessie Makes Raspberry Pi Even Easier to Use 5 Ways New Raspbian Jessie Makes Raspberry Pi Even Easier to Use Following the release of Debian Jessie in July, the Raspberry Pi community has been blessed with a new release of the Raspbian variant, based on the "parent" distro. Read More . This free operating system is available from the Raspberry Pi Downloads page and can be installed on any Raspberry Pi model to date. Note that two versions are available, the Full desktop image and the Minimal image. The latter comes without some of the expected tools, but is a faster download and takes up less space on the SD card.

Writing the operating system is straightforward regardless of what operating system you’re using.

Installing Raspbian with Windows

While Raspbian is downloading (or on slower connections, after), head to Sourceforge to download your copy Win32 Disk Imager. When complete, install it.

muo-diy-raspizero-write

Once you have downloaded and unzipped the Raspbian, insert your formatted (using the SD Association’s Formatting tool) microSD card into your PC’s card reader (or a suitable USB card reader). Run Win32 Disk Imager, and ensure the drive letter corresponding to your microSD card is selected in Device.

Click in the Image File field to find the unzipped Raspbian .IMG file, select it, then Write. Wait until the progress bar has finished and Win32 Disk Imager informs you that writing has completed, and then safely remove the card from your PC. You can now pop it into the powered-off Pi Zero, connect the power cable and boot up. Our full guide for using the Win32 Disk Imager to install Raspbian provides even more information How To Install An Operating System To Your Raspberry Pi How To Install An Operating System To Your Raspberry Pi Here's how to get a new OS installed and running on your Pi – and how to clone your perfect setup for quick disaster recovery.

Installing Raspian with a Mac

Apple Pi Baker provides a similar feature set as Win32 Disk Imager. Once your card is inserted and recognised, select it from the list on the left; then select your downloaded .IMG file from the right, and click Restore Backup.

applepi-baker-startup-screen

Don’t forget to eject the card when you’re done to prevent data corruption.

Hey, NOOBS, Flash This!

Rather than install Raspbian this way, why not take a look at NOOBS? This software, which can be copied straight onto a formatted SD card, contains a number of different OSes (including Raspbian), ready for you to experiment with.

muo-rpi-noobs-sdformat-noobsui

Due to the modest connectivity options of the Pi Zero, we would advise the full, offline NOOBs installation, which means that each of the operating systems offered with NOOBS is available for your Pi Zero without additional downloads. If you have a full-size Raspberry Pi, you can also use the online NOOBS installer to complete the installation, and then insert the card into your Pi Zero.

For the best results, Raspbian Jessie should be your preferred OS, at least at first. How you install it is up to you!

Pre-Installed SD Cards

Don’t have an SD card for your Raspberry Pi Zero? Missing a card reader, or don’t have the bandwidth to download a copy of Raspbian? Don’t worry – you can purchase microSD cards from Amazon with NOOBS pre-installed!

Connecting the Cables

With your Pi Zero operating system writing to SD card, now is the time to connect the cables. If you want to see output from the Pi Zero on your monitor, connecting the HDMI adaptor cable should be your first step (unless you already have a suitable Mini-HDMI cable).

muo-diy-raspizero-on

Are you planning on adding a USB device? You might opt to add a wireless dongle, as the Pi Zero doesn’t ship with built in Wi-Fi or an Ethernet port. With a Wi-Fi dongle added, you’ll be able to connect to the Pi Zero remotely via SSH, for instance, although note that this will require system resources and if you opt to power the Pi Zero with batteries Pi to Go? 3 Ways of Powering a Raspberry Pi for Portable Projects Pi to Go? 3 Ways of Powering a Raspberry Pi for Portable Projects Want to get your Raspberry Pi out of the house and involved in some mobile projects? You'll need a battery of some sort – but there are several options available. Read More , any network activity will reduce battery longevity.

Getting the Pi Zero Online

If you’re installing with NOOBS, you’ll need to take care to download the full, offline installer, as opposed to the lighter option. This will ensure you actually have an operating system to install, as opposed to a menu giving you a choice of OS to download.

Should you choose the lighter, online installation with NOOBS, you’ll need to first ensure that the Pi Zero is connected to the Internet. In the absence of an operating system with which to setup wireless networking, you’ll need to find a compatible USB Ethernet adaptor, which might be micro USB compatible, or else standard USB connected to the an adaptor.

However, other options exist. One popular alternative is connecting a mini Ethernet PCB to the Pi Zero’s GPIO, but this isn’t an easy task for beginners. One thing to keep in mind is that connecting an Ethernet cable into the Pi Zero will almost guarantee instant connectivity; connecting a wireless dongle may not.

One shortcut you can use is to setup Raspbian and your wireless USB dongle on a full size Raspberry Pi. With the wireless card setup – the SSID is detected, the username and password input, and the connection made – you should then shutdown the Raspberry Pi, remove the microSD card and insert it into your Pi Zero. Similarly, remove the Wi-Fi USB dongle and attach this to the Pi Zero and boot up. If all has gone smoothly, you’ll have saved time downloading, installing and configuring Raspbian for the Pi Zero, and have the device online immediately.

Mouse and Keyboard Options

How will you control the Pi Zero? The obvious option would seem to be with a mouse and keyboard, but the limited USB connection options (unless you have a powered USB hub connected) may put a dampener on this.

Other options for entering text and controlling your Raspberry Pi Zero are available, however, using SSH or VNC.

Should You Connect a Monitor or Not?

The initial response to anyone reading this might of course be “well, how else will I be able to control the Pi Zero?”. But you don’t need a monitor connected to the device in order to control it.

While the Pi Zero does an HDMI connector, you may find that this isn’t compatible with your TV.

A Pi Zero Case

With your Raspberry Pi Zero connected, booted up and some method of controlling it established, it’s time to find somewhere to keep it safe. Four mounting holes are provided in the PCB which allow you to screw the Pi Zero to whatever project you happen to be working on, but you might also require a more reliable, sturdy home for the little computer.

A collection of Raspberry Pi Zero cases are available on Amazon, such as this compact, affordable offering:

Adding Pins to the GPIO

Your Raspberry Pi Zero is capable of doing most of the things that a full-sized Pi can do… eventually. Straight out of the box, however, you’re a bit limited thanks to the lack of GPIO pins.

Pins are either shipped in a separate container, or if you were lucky enough to get the Pi Zero on the front cover of MagPi magazine, they’re not there at all. As a result, you’ll need to order a suitable array of pins, not only for the GPIO, but also for the four pins next to the Raspberry Pi logo. These pins for the run/reset jumper, when fitted, enable you to turn off your Raspberry Pi safely How To Add a Reset Switch To Your Raspberry Pi How To Add a Reset Switch To Your Raspberry Pi Removing and replacing the USB power cable puts undue wear and tear on your Raspberry Pi, particularly the power port itself.

So, with the Pi Zero, all of these projects can be improved, either saving space or weight.

The Raspberry Pi Zero: A Must Have for DIY

DIY computing and robotics projects were given a shot in the arm by the original Raspberry Pi. Filling a surprisingly large niche that no one had previously identified in a satisfactory manner, the Pi became the de facto minicomputer, squeezing itself into spaces previously occupied by old PCs and discarded netbooks.

The Raspberry Pi Zero takes this success a step further, shrinking it down and introducing user choice for hardware components. Essentially a Raspberry Pi A+ on a strict diet, the Raspberry Pi Zero – costing just $5 – is the computer that everybody with an interest in educating children in computing and building DIY projects should own.

The fact that the price point is so cheap it can be bought for the price of a cup of coffee – and (in an industry first) mounted to the front of a magazine – means that more children around the world can get access to it, and develop the skills that can help to push their lives away from poverty.

    My fist project is a audio-line switch for 4 inputs (PC, RasPlex, Airplay and XBox360) and 2 outputs (Speaker and Hedset).
    The device has a OLED-Display to show what is active and what is switched.
    Also a switch for the Mic (ON/OFF) is integrated.
    Because the device is smale, i used a Pi Zero.
    Test-system (and Software) is working now and i need the two prints for the relais, driver and buttons.
    The Pi Zero is perfect for such a smale device ;-)
