ESP32 Pico Kit V4.1 hardware serial pins what numbers are they on the board?

Hi,

ESP32 Pico Kit V4.1 hardware serial pins what numbers are they on the board?

I've been trying to find them in the documentation.
The closest thing I could find was U1TXD and U1RXD (IO pins 10, 9)

Does a hardware code example exist somewhere of a hardware serial connection?
I've been trying to hook up a NEO 6M gps module via the serial ports just so I can get a read out on the PC.

Thanks.

In general, the ESP32 pins are highly configurable and I believe the Arduino environment allows you to specify which pins to use for Rx/Tx in software.

But what if I want to use hardware serial are pins 9 and 10 good enough?
Right now all I get is zero display output.
