The Raspberry Pi Zero features a BCM2835 chipset, overclocked to 1Ghz with 512MB RAM, and the same 1080p video output, so there’s plenty of oomph in that little board. It also features the same 40 pin GPIO layout as the Raspberry Pi 2/B+/A+, which you’ll need to solder your own headers to. With it’s small form factor and reduction in connectors, the Raspberry Pi Zero only uses ~ 140mA at 5V!
Unlike it’s larger brothers and sisters, the Raspberry Pi Zero has an unpopulated GPIO, unpopulated composite (RCA) header and an unpopulated reset header. There’s also no DSI screen port, no ethernet, no analogue audio and no full sized USB ports. Instead, the Pi Zero features a micro-USB power port, a micro USB OTG host port (for peripherals e.g. WiFi dongle), and a mini HDMI port for video.
HAT Compatibility Note: The Pi Zero is fully compatible with all HAT breakout boards, as it features the same 40 Pin GPIO as the Raspberry Pi 2/B+/A+
