[pcb] 💡expose uart1 tx pin on swd port

[jalmeroth]

Hey there,

my current development setup looks something like this:

Since I have the picoprobes attached, I would like to have the stdio output on uart1 instead of using the deskhop CDC device.
Therefore I would like to have an uart1 tx pin (e.g. GPIO 4) next to the SWD connectors, so I can get rid of the floating, grey cable in the picture.

Would that be possible?

Thank you very much!

By all means, I need to look into pcb 1.2 soon anyway, have some outstanding bugs. Also, pico2 is out and that needs to be tested 😃 cool picoprobes, btw have you ever experienced picoprobe port just going bad after a few weeks?

Awesome, I was just about to order some new pico2`s!

No not really, but I must confess that I basically use them as tty and occasionally to update the firmware via openocd. Can you narrow what "going bad" means?

Yeah, I've had openocd firmware upgrade stop working for some reason on 2-3 boards, but when I recompiled to use other GPIOs, it started working again for a while, only to repeat. Perhaps some TVS diodes might be a good thing to install there :)
