although it says it needs a Pi 3 the google AIY kit is just as happy with a Pi Zero (V1.3)
A couple of minor points!
- They dont give any info about which way round to install the LED lamp (you just need to look at how the leads are wound round the lugs on the holder more loops = + which I assume should be connected to the red wire)
- Some of the set up stages using the google website took a number of page refreshes as the site seemed sluggish (admittedly that could be due to doing the setting up on a Pi Zero)
- Also if you use a Pi Zero in a PiBow case everything fits but its a tight fit (I couldn't be bothered to take it off)
And of course the beauty of the cardboard case is that its an ideal place for stickers!!! That was after I added an extra hole in the back for the power cable.
