Version 3

    PiZero_frontandside-small.pngTwo models of Raspberry Pi inside 12 months spells an exciting year for hackers, makers, coders and tech heads around the world, and there are certain questions that immediately spring to mind when we hear about a brand new board.

     

    We'll get into a lot more detail about the Pi Zero in coming days, weeks and months, but right now here's a quick guide to get you up to speed as fast as possible.

     

    What is the Raspberry Pi Zero?

    While the Raspberry Pi 2 marks the top end of the platform's tech specs, the Pi Zero takes the opposite approach. This is, for all intents and purposes, an entry-level model that's been reduced both in price and size (being three times smaller than the original Raspberry Pi 1 series).

     

    The Raspberry Pi Zero: Technical Specifications

    • CPU: Broadcom BCM2835, which can run at up to 1GHz.
    • RAM: 512MB
    • Power: 5V, supplied via micro USB connector, drawing 160mA (even when connected to an HD display).
    • Dimensions: 65mm x 30mm x 5mm
    • Video & Audio: 1080P HD video output. Audio output via mini-HDMI connector.
    • Storage: MicroSD card.
    • Operating System: Linux, installed via NOOBS.

    The Raspberry Pi Zero: Inputs and Outputs

    • MicroSD Card Slot: The Pi Zero gets its storage space from a MicroSD card, which you'll need to install the operating system on.
    • Mini HDMI: Video output for the Pi Zero is by way of a mini-HDMI connector. In terms of their operation, these connectors perform identically to their larger versions. N.B. A mini-HDMI to standard HDMI adapter is included with the Pi Zero from element14.
    • Micro USB: You'll notice there are two micro USB connectors on the Pi Zero. One is for data (the connector on the left, if the MicroSD card slot is on the left), and one is for power. Don't get them mixed up. A micro USB "On the Go" to USB adapter is included with the Pi Zero from element14 so you can connect a USB hub, and therefore all your peripherals (keyboard, mouse etc).
    • GPIO: The Pi Zero has the same 40 pin General Purpose Input/Output connections as the Model A+, B+ and RPi2, but the connector pins are unpopulated. So if you want to use the GPIO, you'll either have to solder the required pins in place, or solder your connections directly to the Pi Zero.
    • RUN Mode Pins: There are two unpopulated RUN mode pins, which can be used to connect a reset button to the Pi Zero. Again, you'll either have to add the pins yourself, or solder a button straight to the board.
    • Composite Video: Here's an interesting one. There's an RCA composited video output via two (unpopulated) pins, so you can hook the Pi Zero up to older display equipment that accepts a phono plug as an input. You can check out the RCA video output in use in our Raspberry Pi Zero Retro Gaming System project right here.
