How many Shields can you install?

I was wondering if there is a maximum number of shields that you can install before there are issues? I was planning on installing 7 on a TinyZero, including the GPS shield, the Combined Sensor Shield and the 433MHz Shield.

If there would be an issue with that many, please let me know, as you would be saving me quite a bit of money!

There shouldn't be an issue as long as all the shields don't have any conflicting pins. You can check this with the compatibility matrix:

Physically, if you're going to be moving this stack around at all it might help to have a mounting kit between some of the boards:
You could use one mounting kit and space out the components as I have poorly portrayed in the attached image.

Additionally, depending on what boards you plan on using and project goals, it might help to use the Wireling board format instead of TinyShield:

If you want to share more on what boards you want for your project or what the end goal is, I would be happy to recommend any hardware setups that might work better / be cheaper.

Let me know if you run into any questions on compatibility.
