RPI5 serial console? - Re: Raspbery Pi support (release notes/wiki page) update? (RPI5)

Hi,

Thanks for all this info.
I received my RPI5 and noticed that the default serial/UART is not on GPIO anymore, but via a dedicated 3-pin JST HS (?) connector.

Do you use some cable on this? What do you use?

I found this: https://www.raspberrypi.com/products/debug-probe/
Does somebody know about a simpler JST-USB connector for serial console on RPI5?

Regards,
Ronald.
