This is an inexpensive 3-foot-long HDMI to Mini HDMI cable that you can use to hook up your Raspberry Pi Zero W to a suitable monitor or TV. Heck, you can hook up anything you want with it! Mini HDMI is not that common of a medium right now, but in the interest of saving space it can come in handy!

Transmits audio/video like nobody's business! 5 stars for the cable, 7 for always-awesome service from Sparkfun.
It works with my Raspberry Pi Zero W. It's a plug and play. Good quality.
