Re: How much amps do I need?
That level shifts control signals. So if the driving device, such as a raspberry pie is on 3.3v and the neo pixel is on 5v then the signals will interface correctly.
Often you will find that the slave device even on 5V will happilly accept 3.3v control signals directly.
Can you say what the LED neo-pixel part is and what you intend to use to drive the interface line(s). Then I could check the levels for you.
Here's a useful resource: https://learn.adafruit.com/adafruit-...c-of-neopixels
