Uart LV-TTL

Hi, i want to implement a Uart LV-TTL (3.3V), something like in the Raspberri Pi (only TX and RX, like the picture below) in a imx6. I was wondering if i could use pins directly connected to the SoC (with the proper voltage, off course), and get the same results as in the raspberry.

i have seen some schematics where the uart is connected to a RS232 port with more pins

and i´m confused, will it work if i only use TXD and RXD directly connected from the SoC?
