XIAO SWD connector

Products & Technology XIAO
#1

Hi,

I have just received my XIAO.
What I found awesome is that there are SWD I/O are exposed, but on testing pads.
I would like to know if you could provide an Eagle library with SWD pad footprint or any simple solution which could cleanly expose those pin to a standard SWD 10 pins connector (I don’t wan’t to solder crappy wires on the pads.), because the SWD pads are not aligned on a 2.54mm grid.

I could eventually make a custom carrier board. Which connector do you use on Seeeduino XIAO Expansion board (spring contact)?

Thanks by advance,

Thomas

It seems the Seeeduino XIAO Expansion board already features pogo-pins for debugging.

Please refer to

Glad to know that you find the exposed SWD I/0 design useful for you.
The spring contact we use in SeeeduinoXIAO Expansion Board is customized, and purchased from designated contributor at a minimum order quantity. It well fits pin header of both 6mm and 5mm height. If you think SWD function is necessary for you, it would be highly recommended that you get one. :slight_smile:

Thanks for your anwser.

I have already seen the Expansion board, but not available yet. Also I would like to design my own expansion board, so I’ll need dimensions or any informations to be able to connect the SWD pins.

Thanks for your anwser. Could you please provide the cotations to be able to well position the pogo pins ?

I think it would be great to have a XIAO footprint with those pins exposed in your Eagle library :slight_smile:

Ok, thanks, I guess I can make cotations from the brd file.

PS : it looks like this is not the latest design which is available on the link you gave (missing reset and gnd test pads)
