Introducing Raspberry Pi Zero W

You asked for it, you got it: a wireless-enabled Raspberry Pi Zero. Out right now

The Raspberry Pi Zero has proven to be one of the most popular and sought-after versions of the Raspberry Pi since it came out in November 2015. However, many people thought it lacked one very important feature: inbuilt wireless internet. As of today, the Pi Zero lacks it no more: let us introduce you to Raspberry Pi Zero W.

The new Raspberry Pi Zero W will cost $10 and is launching in the UK, today, at £9.60 (including VAT).

You'll only notice minor differences in the layout of the board

It’s almost identical to the previous Raspberry Pi Zero v1.3 (the one that added the camera connector) – importantly, all the chips and components are still only on the top side of the board.

Wireless antenna

While the radio chip on the Raspberry Pi Zero W is the same as the one on the Raspberry Pi 3, the antenna is completely different. Instead of a little white chip that contains it, the antenna on the Pi Zero W is printed into the board.

The antenna is the discoloured triangle at the edge of the board

We spoke to Roger Thornton, principal hardware engineer, about the new antenna:

“The Raspberry Pi 3 antenna is a surface-mount component,” explains Roger, “whereas the Zero W antenna is a resonant cavity which is formed by etching away copper on each layer of the PCB structure.”

The technology is licensed from a Swedish company called Proant (you can see the credit on the reverse of the Zero W board).

“They’re very clever boffins,” says Roger. “It’s a really neat design.”

The triangle recession in the board is known as the ground plane. This free space is used to interact with the radio waves. They resonate in this cavity at just the right frequency. The two components at the small side, right up by the board, are a couple of capacitors which capture the radio signal.

  • Jason Morris

    That’s slick with the antenna…surprised no one else has done it…

  • Saxeee

    Great news! Wi-fi was a must-have feature on the Zero. Now it’s the perfect controller for a 3D Printer with Octoprint. The only problem is the maximum order quantity stil locked to one on all listed European store!

  • Now Pi3-0W and take my money!

  • and brazil???

  • Mike

    But you can only buy 1. What if you want to build something with it and you need like 20?

  • Yash Deep Hinge

    Can I use it for an internet tv?

  • TheRealTachyon

    This is awesome. Just what the lineup needed.
    Now all we need is a Raspberry Pi 3 WITHOUT built in wireless and the lineup is complete.
    In fact I’d love to see a Pi 3+ that has 2GB RAM and no wireless.

  • BerkmanLord

    It would be great if you could remove the Turkish reseller from the list. They are refusing to sell 0W on it’s own. Apparently out of stock.

    But hey, they are happy to sell “Maxi Pack” which includes a terrible USB Hub, a generic power & HDMI adapter for $60.

    Disgusting.

    Have to say, amazing device. Just need to find someone more ethical to buy it from.

  • Mike Newham

    Hi there, just wondering, i have a Macbook Air that has a USB 3 port that can output 900mA over a proper USB 3 cable.

    Will this provide enough power for the ‘Pi Zero W’ and can i do data transfer over it. I.e. ‘headless’ mode at the same time. Cheers!

  • cwo3ret

    yes – RNDIS gadget sharing (Prefs->Network, etc.)

  • Preston Gallwas

    So 1.5 months later still can’t buy in the US because “Out of stock”… but all the kits are suspiciously in stock. Too bad I don’t need another lump of unused cables or adapters…

  • Saeid S

    Hallo,
    I need an official DATASHEET for Raspberry Pi Zero W. I wanted to ask you, where could I find it?

    In all friendship,
    Saeid,

  • Kevin Shumaker

    Microcenter has the boards in store, in stock. Just grabbed one for $10. Very nice so far.

  • Preston Gallwas

    Sadly, none in WA and in-store pickup only.

  • Joerg Bauerfeld

    Just bought one, can’t believe it, it has a DUAL BAND!!! wifi implementation … so you can run Bluetooth and WiFi without any interference … this thing rocks and is dirt cheap!
