Raspberry Pi Zero W
The Raspberry Pi Zero W takes the beloved and extremely popular Pi Zero and adds wireless LAN and Bluetooth, making it perfect for embedded Internet of Things projects. Unbelievably the super-small and super-affordable Raspberry Pi just got even smaller and even cheaper! The Pi Zero W has the heart of a Raspberry Pi on a tiny 65mm x 30mm board. With mini-HDMI, micro-B OTG USB, and the same 40-pin GPIO it still has great connectivity although you’ll probably want adapters (micro-B OTG USB and mini-HDMI) to help you hook it up to your existing devices.
