Hey, so I just bought a camera module and a fingerprint scanner for my Uno. The thing is, they need 3.3V from the digital pins, and I don't want to have to change any of the code in the IDE for it. I was thinking about buying some of these 3.3V voltage regulators. There are a few things I would like to know before buying them:
1: will they distort the feed for the sensor, so pretty much will they change my readings
2:it says "3.3V 1.3A." Should I consider getting a higher or lower amperage one of these?
and 3: will it even do what I need it to do?
Thanks for the help!
