[I'm looking at the parts I can order and parts I can find in KiCAD I thought I would have an option to power the board from USB C only because there is that higher amperage option when you want to drive a lot of relays. Then I thought it would be trivial to add the USB data lines. The problem I have is I want to hand assemble the board and I only have an iron so with that many pins on the USB connector I'm starting to rethink the USB C port. At least until I figure out what I really need. Using a barrel jack for power too could be an option I need a power pass through option.
I often hand-solder USB-C sockets. As it happens, the particular ones I have on my shelf are easier than the USB-micro-B that I also have on the shelf (though these are historical choices and you could probably pick other ones that are the opposite way round).

All you really need is one with only a single row of pins and for them to be not too far under the metalwork.
Are you familiar with drag-soldering technique (using flux to get the solder to stick to where you want it)?

This part is power-only:

This part is power-plus-USB2-pins (ie. what you usually want for RP2040 use):

Both have all the pins sticking out at the back and fairly easy to get at with the iron.
Thank you! That is great!

I've only really done SMD soldering a few times and what I got to do it was liquid flux and the wick. I did my SOP chips this way and everything worked out I used mostly through hole last time but I feel I can get better results if I use more SMD this time.

So with the USB you need these resistors to make it work? Is this correct?
