What is the ideal power supply for this module? What do you use that works ok?
Will the AMS1117 work?

Yes, that will work. However, ignore the entire description.
That is NOT a buck regulator - it is a low-dropout linear regulator. Thus it will waste power as heat - the more current you draw the hotter it will get.
The '1117' range of regulators are pretty much ubiquitous. I use them in a wide range of products and situations where power consumption isn't critical (i.e., not battery based products).
For lower power requirements you want to get a real buck regulator. Something more like this: http://www.ebay.co.uk/itm/301842020065
Note that it's an adjustable module, and you will need to first use a multimeter to adjust the output to 3.3V before you connect it up.
Because they are adjustable they are a great thing to keep around since you can use them for all sorts of different situations.
