    Greetings!

    As many of you, I have been struggling with my setup re-done it a few times, bought numerous variants of the same stuff and blew my budget out the window a long time ago. That being said I have and still enjoy the project and appreciate ALL YOUR ACTIVITIES on forum.

    My next challenge is a level shifter.
    Have tried various solutions to stop flickering and now think this is the last shot.

    I either didn't look properly or am just that NOOB that I can't get any conclusive info on sites forums etc...

    Living in Portugal acquiring micro electronic / robotic materials is a challenge.

    I was wondering if any of the following to level shifters is ok or recommended.

    FYI Don't know.if it's relevant but I use a LED strip from SparkFun

    Happy geeking

    Thanks for the quick replies one of the reasons I love this forum!

    I have thought of that but really don't wanna w8 30+ days for delivery.

    Let's see how it goes.

    I know this is completely unrelated but is there any update on the HDR issue ? Or is the only work around still the HDFury products ? ($$$)

    So

    I just ordered 2 of the level shifters I'm case I FUBAR 1 of em (SparkFun ones, since the other are sold out)

    How does one connect this ?
    Sorry like I previously said I haven't found enough info to reassure me that I know how I'm going to connect this.

    Does the level shifters itself have to be attached to some sort of board? ( or is that just when using and Arduino )
    Is just wiring that I need to do?
