“I'd have preferred a mini B USB connector, instead of the micro one, because they're much more robust. Also, the silk screened pin identification is only on the side you can't see, when it's plugged into a breadboard.
Apart from those things, they are a great deal, so I bought some more. I don't know Python, and have used C and C++ for decades, so I'm now using earlephilhower/arduino-pico from github. That lets me use it in the Arduino IDE, as a more powerful arduino - a lot faster, and with two CPU cores.”
“Fairly easy to use, powerful and lots of flash. Works with Eclipse and you get source level debugging if you use a second Pico as a picoprobe.
Don't miss the pico project creator program that helps when creating your own projects, it saves a fair bit of messing around.”
