There is one UART with one tx and one rx pin easily accessible.

I think there is another serial module in the Pi, but it uses the same GPIO pins.

There are two UARTS. A "mini" UART and a PL011 "full" UART. They are both available on various GPIOs as different ALT functions.

The BCM2385-ARM-Peripherals PDF shows how to use both of these and which GPIOs they can be on. As to which pins of the CM they are on, that depends on which ones you program them to use.

Each of the UARTs is available on three different sets of pins http://elinux.org/RPi_BCM2835_GPIOs

I think the default UART or console would be the best option as this needs minimal configuration.
Pi[NFA]=B256R0USB CL4SD8GB Raspbian Stock.
Pi[Work]=A+256 CL4SD8GB Raspbian Stock.
My favourite constant 1.65056745028
