The Raspberry Pi Zero

The size of a Raspberry Pi Zero is half the size of a Model A+. This is ideal for embedded projects where size and power requirements are stringent. Here are the specifications for the Raspberry Pi Zero:

• A 1-GHz, single-core CPU
• 512 MB of RAM
• Mini HDMI and USB on-the-go ports
• Micro USB power
• A HAT-compatible 40-pin header
• Composite video and reset headers

Here is an image of the Pi Zero, obtained from www.wired.co.uk:

There are two ways in which we can connect the Pi Zero to a display:

• Using mini-HDMI-to-HDMI converter, shown here:

• Also, we can use VGA for display. For this, we need to use a mini-HDMI-to-VGA adapter.
