The Brand New Raspberry Pi Zero WH Wireless (with Pre-Soldered Header) is an ultra-low-cost and ultra-small variant of the original Raspberry Pi. It’s tiny, measuring just 65mm x 30mm, and is perfectly designed for embedded applications, wearables, prototyping and any other Pi-based tinkering you can think of, on a micro scale! The Raspberry Pi Zero Wireless features onboard Wireless Internet & Bluetooth for all your connectivity needs!

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 too. With its 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 analog 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.
It’s perfect for everyone who doesn’t own a soldering iron or who wants the soldering legwork done for them.

What can you do with the Raspberry Pi Zero WH.!
What can’t you do? Am I right?! The small size of the Zero W makes it perfect for projects with minimal wiggle-room. In such projects, some people have no need for GPIO pins — they simply solder directly to the board. However, there are many instances where you do want a header on your Zero W, for example in order to easily take advantage of the GPIO expander tool for Debian Stretch on a PC or Mac
