UART on pidog robot hat

Hi
I notice that the UART on the robot hat appears to be unused on the pidog ?
I’d like to connect devices to the UART, but although the UART is referenced in the hardware documentation, I cannot see any indication of it in the software.

Could you please let me know how to access the UART? or point me to the requisite software?

Thanks

Ahh. I just noticed this in the HW description…

It connects to the Raspberry Pi’s GPIO14 (TXD) and GPIO15 (RXD) pins.

That’s enough to get me running. I wasn’t sure if Sunfounder had added their own UART to the hat.
