Connecting RPi & Arduino Over Serial GPIO : Query.

Is there any way to connect RPi & Arduino over serial GPIO without using Dual-Logic Level converter (5.0V <-> 3.3V) ?

If there's any then kindly teach me the method.
Tell me the correct method, I don't want my Pi get bricked.

    Do feel this will work out for you?

    I found this as a way of connecting the Rpi and arduino I am looking for other possible I will post as I find them here

    This is way too much of mindfuck, man.
    I wanna keep it simple for that. I can connect RPi with Uno over Serial GPIO using Logic Level Converter, but now I simply wanna know that, is there any other way of connecting Pi with Uno w/o using LLC.

    I will be damned if I use that instructables method just for connecting Pi with Uno (because simplest way is available) :


    Okay there are few configurations to be done. But it's still simple than the one mentioned in instructables.

    Back to query, Any other method of connecting Pi with Uno w/o using LLC ?

    the volt variation does need a LLC. nevertheless, there seems to a hack available (involves, replacing the regulator ) if you want to take the plunge here :

    If you are using Pin in one direction only then I think voltage divider is the best option.

    Explain me with circuit diagram ?
