dose anyone know which connectors connect sda and sdl... i know that they both go to a4 and a5 but which ones do they individually go to

Hi.

Keep practising on how to ask questions. I have no idea what you are asking for, and what board you're talking about.

Have a look over here (click !) ?

Is that possibly what you are looking for ?

.. as MAS3 said: we can only guess what you are asking for.

Is it the PinOut of a given Arduino board (what type?) or are you looking for the ATMEL chip PinOut (what Atmel microprocessor type?).

Or just simple: SCA -> A4 SCL -> A5

??? what does come close to your question ???

Thanks for saving me some time. I was just about to go looking for that same photo. On my UNO R3 boards, I always use the new SDA and SCL connections. (Not available on earlier UNOs.)

Well, i’ve just pointed to another great thread by Nick Gammon.

Nick is the one that should receive all credits for it, so thanks again Nick, for all your efforts you put into this community.

@brenden_nerd_: Care to let us know if this is of any help (and why not) ?
