2. Setting up your SD Card

When setting up a new Raspberry Pi, you will need to install an operating system (OS) onto your SD card. There are many operating system options, however the official and most commonly used is Raspbian OS. For Gizmo you will set up a modified version of Raspian.

When setting up a new SD card yourself, we recommend using NOOBS (New Out Of Box Software). It is an easy installer to get a Pi up and running quickly (including Raspian OS). For information on how to set up with NOOBS, use this guide.

2.1. Downloading your Disk Image

Usually, you would download a zipped image file directly from the Raspberry Pi website.

However, for Gizmo we have already added the drivers required to use the touchscreen. We followed this guide from the manufacturer. You can use it to find additional steps to modify the configuration of the touchscreen if you need to.

2.2. Flashing your Disk Image

  1. First you must format (wipe) the SD Card. Download SDFormatter here .
  2. Use SDFormatter to format the SD card. Please be careful and make sure you select the correct drive letter.
  3. Download Etcher if not installed.
  4. Use Etcher to flash the image to the SD card.
    • Please be careful that the correct drive letter is selected.
    • On Mac: if you backed up the image yourself (see Chapter 8: Backing up your SD card) you may have to change the file extension from “.cdr” to “.iso”
  5. You’re done! If all has gone well the Raspberry Pi should now boot when started with the new SD Card.


Your Gizmo Raspian OS has been optimised for the 5 inch touchscreen - so will always display the screen in low resolution (800x480). If you move to a full size screen you should reverse the steps taken here to avoid potato resolution.
