ABRA , where I got mine had "a pile" of them!

After I read your first post about getting them at Abra I made that pile a bit smaller!  Pretty pricy when you factor in the 16 dollars shipping, but I'm glad to have them.

I suspect that in a few months they will be available everywhere for a reasonable price.

I wanted an outing so I actually went to the store to pick them up, in the snowstorm,  a couple of weeks back! Always an adventure!

I bought 25 of them for $99.00.  They actually sent me 26.  I guess I got in under the wire.  My plan was to keep a couple and resell the rest on ebay.  Might as well pay me as someone in China. 😀 😀

Why not hook them all together and see what you can do with 676 GPIO ports at your disposal?

Firstly some related info others might be interested in :

The printed edition of  "Get started with Micropython on Raspberry Pi Pico" published by Raspberry Pi Press has been recalled here in the UK due to mistakes in the coding and a new version will be sent to me from "ThePiHut" with no need to return the original.

A technical query :

Why do Adafruit state "You get a total of 25 GPIO pins (technically there are 26 but IO #15 has a special purpose and should not be used by projects)"

I’ve used GPIO 15 on the Pi Pico without issue. I don’t see anything in the data sheet about it being special. The extra GPIO that I know of is the onboard LED. It has no paired external PIN. I believe it is GPIO 25. This looks like a typo to me. Given the pins start counting at zero, they must be referring to this pin, it is the 26th.

I put a question in the Adafruit forum.  We'll see what I get back.

 

If your code won't compile, have another glass of bourbon. Eventual the problem will be solved.

I've never soldered header pins onto a PCB....wish me luck. Maybe I should have asked the supplier for some DOA Pico's to train on 🤔

@theoutlander

You should read the last two posts I made to @sumanta on the "Soldering Station for beginners" topic.

You might enjoy or even find beneficial.  😎

@codecage I was just reading that! I bought new tips which improved things dramatically - I obviously have a maintenance issue.

That's what that sponge or cleaning braid is for, use it often. 😎

That's called "Trial by Fire." Literally!

Good luck, my friend.

It appears that the pin issue is related to beta releases of CircuitPython.  For details see:

Anyone having issues getting to the video?  At 1:40 PM EDT I can't seem to get it.  Other YouTube videos seem fine.

Edit:  Well when I came back a little later it was fine.  Computers...  Only the Shadow knows!
