The Raspberry Pi Zero (see Figure 1-6) holds two accolades: it's by far the smallest Raspberry Pi, and it's by far the cheapest. Despite its size – roughly equivalent to a couple of sticks of chewing gum stacked one on top of the other – it loses little: the Pi Zero includes the same BCM2835 SoC and 512 MB of RAM as the Raspberry Pi Model B+, running at a slightly faster speed for improved performance.

Caveats apply to the use of the Pi Zero, however. Even compared to the Model A+, it’s cut down: the single micro-USB port and mini-HDMI port both require adapters before they can be connected to standard peripherals; the 3.5 mm AV jack is missing; there's no DSI port, and the CSI port requires an adapter; and the GPIO header, although present, requires pins to be purchased and soldered into place before it can be used.

If you are a Raspberry Pi beginner, the Pi Zero is not the best choice of starter board. When you're more experienced and are looking to add Pi-powered intelligence to embedded projects – especially where size, cost, and power draw are concerns – the Pi Zero should be the first board on your mind.
