3.3V source on SKR Pico about zippy-klipper_config HOT 4 CLOSED

Ah yeah that is totally fair, and is actually probably a better connection to go with for that reason.

That said, I used the connector I did personally because of convenience, as it's easy to access from the outside if you have any kind of case on your board, and mine at least came with a pre-crimped connector that would work without any soldering.

Also, FWIW (and don't take this as applying to everything) but I've found that many components labeled for 3.3V will take 5V just fine, and I knew that was the case with the CAN transceiver I used.

I will add a note about this to the guide though, thanks for pointing it out!

Actually, looking more into it, I don't think the SWD pins are addressable, so you would need to use that 3.3V and maybe ground and still use the UART or another set of pins for the canbus data...

Yes, that is indeed the way I run it, 2 cables go to SWD for power, the other two to gpio 0 and 1, like depicted in your how-to. It works perfectly fine.

I added a note to the guide about alternative pins and their advantages: 4c1e532

Thanks for the suggestion! 👍
