Unbelievably the super-small and super-affordable Raspberry Pi just got even smaller and even cheaper! Pi Zero w is 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.
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.
