Introducing 老师啪啪啪视频 Pi Zero W

The 老师啪啪啪视频 Pi Zero has proven to be one of the most popular and sought-after versions of the 老师啪啪啪视频 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 老师啪啪啪视频 Pi Zero W.

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

It's almost identical to the previous 老师啪啪啪视频 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 老师啪啪啪视频 Pi Zero W is the same as the one on the 老师啪啪啪视频 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.

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

“The 老师啪啪啪视频 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.
