The test points PP22 and PP23 have been moved between version 1.3 and earlier version(s), so I read. I was unable to get one since I live on the "wrong" side of the ocean. Only recently did I find time to drive 1.5 hours one way to get one rpi-0 for myself (V 1.3).
Here is some reading about change of test point locations:

For the fellow saying I should have used pi compute module, you are either an expert electrical engineer, or you have no experience designing or soldering a printed circuit board. Maybe you missed the fact the compute connector has over 200 tiny contacts on a plastic housing. My in-house reflow oven (aka toaster oven on a variac) will be unable to reflow this part. That's shutting maybe 99% diy hobbyists while adding 2 pin holes to rpi-0 will bring maybe half of them back to the game.
I know that RPF wants their pis to teach kids how to program at a price point kids can afford. But seriously how many of us on the forum are kids just barely affording $35 toys? The foundation, in my opinion, has NOT even become close to its goals. That 8 million sales figure is just a way of saying that yeah, computer geeks like ourselves like this little toy just too much. Some of us went back for more boards and teach our kids pis, cause we didn't have this when we were kids.
So if you take that spirit of letting the users decide what to do with your products, I guess the $5 module is just their way of testing the water to see what users can do with just $5 module. Of course you can do your old trick, USB hub, spaghetti cable monster etc. and have a little fun with just another cheap computer. I have 3 laptops, 3 tablets, and a nice smart phone, plus all my pis. How many more computer do I have to have?! But what if some want to use it as a module in a custom system, like a data logger, or interactive toy or some assist system for seniors? Will spaghetti monster work? Maybe that will drive up the sales and new projects and directions people will find after getting this board? Keeping with the goal of making computers, or letting users decide some of the future direction? Arduino LLC is an example where the designers rarely want anything from the community. One thing they did that rpf didn't do is they have maintained their goal to make affordable electronics for artists and hobbyists easy to use. They struck their goal early on. They tried to make computer-like boards also but eventually didn't do it.
