stacking boards wont fit in my project, can someone recommend a cable that would work to connect the boards if there is one?

Ok thanks!

Im using the TINYSCREEN+ (PROCESSOR, OLED & USB IN ONE) setup, like others i want to use it play short videos.  Is there a port on the board to easily add a speaker?   If anyone has added a speaker would appreciate help with setup.  I'm not talking a big speaker(Im aware of the board available for that) I'm just referring to a small speaker like the one in the arcade.
