I purchased 2 Raspberry Pico 2W. To try the RISCs.
The 3 things that I want to get going first:
debug session on 1 RISC with PicoProbe FreeRTOS SMP running on the 2 RISCS use 3 PIOs (I used the 3rd pio with the stepper motor design I made earlier)

Sakura Pen-touch. I have it for at least 10 years. Still going strong.
I bought it to retouch silver painted plastic parts, like audio gear logos on speakers.
they are pretty brittle. Plastic is absolutely not thermal resistant
I've tried the black ones and they held up well. I'm using led-free, so high iron temperature. And they didn't give in.
plating layer is not largest as well
These aren't gold plated - looks like some silver-coloured plating applied.
I've done a measurement after approx 20 inserts (not deliberate for this test, but I've exchanged a Pico1 and 2 many times to work on the build process), and all are making good contact./ The receiving headers have been used hundreds of times by now, and are still going strong
