Seeed has a version with an ESP8285 and RP2040, I ordered a dev board which is yet to arrive and a couple of the LilyGo boads from https://www.aliexpress.com/store/1101338392?spm=a2g0o.order_list.0.0.17901802X41Gxo for two with shipping and tax it was $27.06. The nice thing about the ESP stuff is that you can host a web server using the Ardunio framework to set it up and load it. Dr Ting has a version of Forth that loads using the Ardunio framework too. I have brought it up on both the old ESP32...

Nice. Is that with the version bundled with Mecrisp?

The numbers you are asking about are the function numbers. They appear in a chart on page 13 of the RP2040 Datasheet. You read them across the top. They appear as F1, F2, F3 etc. The chart is repeated on page 236. I always thought the chart could have been presented clearer. Adding the F to the function numbers made it more confusing than it had to be.

Hi Jose, On page 5, about half way down the page, is a PWM example where I set the control registers for PWM by writing a 4 to the control registers for each of the pins. You could mimic that, but write a 2 instead for the UART. Page 243 of the RP2040 Datasheet is the beginning of the list of status and control registers for the GPIO pins.
