Well, the parent commenter was talking of the RPi3. Android Things doesn't support the Raspberry Pi Zero W.

In the context of my comment, of going to production, the Pi Zero W has the problem of availability / supply chain. So if you plan to manufacture a lot of devices, not only are they hard to get, you get low-volume pricing instead of discounted.

The Zero wasn't mentioned. There is a Raspberry Pi 3 compute module, and I suggest you look that up if you think I am talking about a Pi Zero.

Ah, I see! Not sure if you're the same user as the ones above, but the Compute Module 3 doesn't come with networking chips, so it's a no-starter for Android Things.

The RP3 compute module gets plugged into something else. That something else is free to have Ethernet.
