Custom shields overview?

HI All;

would it be possible to get an overview of the custom shields? i see some topics that are related to this such as the indoor air quality monitor, the NFC shield but since there are 5 backers, can you provide me/us with an overview of what the 5 custom shields will be?

also, if i like one of those?could i buy one?

Hi Korneel,
Zach mentioned his thoughts on selling the shields here :

@korneel We are still scoping some of the custom shields out but all the ones we’ve worked through so far we will be making available for purchase!

The NFC shield and the indoor air quality monitor are the furthest spec’ed out; the third is here:

The other two are still in development behind the scenes.
