Noob question about UART

[Klairm]

Hello, I'm really new to hardware hacking, and I was planning to start with UART on a TV Box to get a shell and see what can I do, so i have 2 models of a TV Box , and one of them, the oldest one, has UART points even tagged, which is good (I already bought UART to TTY/USB and dupin cables for test this) , but looking to the new one I didn't found nothing that clear like the oldest one, but I seen this 6 pin connector , and i was thinking if a UART connection can have 6 pins?
