This is the smallest Raspberry Pi today. The board is only half in size compared with the Raspberry Pi Model A +, but has to offer a lot more! The Raspberry Pi Zero W has wireless connectivity on board in the form of onboard Bluetooth 4.1, BLE and WiFi. The board is only 65mm x 30mm x 5mm wide, contains a mini camera connector, a microSD slot, mini HDMI, 2x microUSB (USB and one for power).
Like the A + and B + W Zero Raspberry Pi has a single core CPU at 1GHz and 512MB RAM. The GPIO header is not soldered so you depend on your project can determine whether a header must be soldered on, and what kind. This gives you much freedom you how to use the P Zero.
The small size brings some limitations with it. To deal with the Raspberry Pi Zero to work, you need a mini HDMI to HDMI adapter and a microUSB OTG cable.
BCM2835 (same as the P 1), but geclocked at 1GHz (40% faster)
۸۰۲٫۱۱ b / g / n Wireless LAN
Bluetooth Low Energy (BLE)
mini HDMI connector
microUSB for data
microUSB for power
Mini Camera Connector (required camera adapter cable)
unsoldered 40-pin GPIO header (same pinout as the other Pi’s)
Dimensions are 65mm x 30mm x 5mm
