Pi Pico debug wire help

Hi @videogame95,

I haven't got one, so this is just an observation, not a recommendation. Raspberry Pi seem to have a debug probe. I am attaching details from a UK supplier. Hopefully it helps you to track down a supplier nearer you, if you are interested.

I would also try Googling for articles about the product, before ordering.

Note the Pico has two options when it boots, and sometimes it picks the wrong one. Sorry, I haven't looked into this properly, so I am not in a position to provide you with am answer. I suggest you look for articles on 'bootsel', to find out how to check and change this.

Good luck and best wishes, Dave

@videogame95 You really need to provide a better explanation of what is happening. Something along the line of.

1. I expected the PICO to do X

2. But it does Y.

ALSO, if you are running a sketch, include it in <> plus if you are using someone else's wiring diagram include a link to it.

Wire size technically is a function of current, voltage, temperature, clas of covering and a few other minor things, but if you are talking about a PICO class device that operates in the few milli-amps, any wire from 30AWG to 20AWG is good.

@zander HI my Pi Pico has a white very small connection for 3 wires to debug I need the connection size for  connection see picture.

  My Pi Pico has a white bloke on it the picture is for debugging any help with connector size.

@videogame95 I have dozens, maybe even 100's of those kind of connectors. They are jST but the problem is what size. You could just use dupont wires, they come in M-M, M-F, and F-F so one of the F would connect to the PicoProbe the other either M or F depending on your header arrangement.

If you do not want to go the dupont route, see if you can match up from the following page https://www.mattmillman.com/info/crimpconnectors/common-jst-connector-types/

Hi @videogame95,

 If you look at the documentation on the web for the Pico debug board that I mentioned previously, perhaps you will find the answer to your question on plug sizes?

Start with :

https://www.raspberrypi.com/documentation/microcontrollers/debug-probe.html

plus the same page includes a second reference ...

 which goes to https://datasheets.raspberrypi.com/debug/debug-connector-specification.pdf

Good luck, Dave

@davee thanks dave

@davee Good find Dave, those little connectors are a nightmare. I think I have at least a dozen and still don't have the right one sometimes.
