I like that there are a huge variety of them and they can be directly soldered to a PCB assembly with their castellated pads. I have many of the variants. I have a few of the newer ones that I haven't had a chance to try yet - ESP32C5, RA4M1 and nRFL15 Sense. I like that most of the newer boards have battery support. It is also nice that they are compatible with Adafruit QT-PYs. Adafruit has some nice add-on boards and a couple of RISC variants.

That would be a great tool for development boards in general. Like many other community members, I have so many that I can’t keep track of where they are. Can’t even keep track of where all my projects are…
Unfortunately, I don’t have the energy to build or manage such a vending machine but I’d love to have one. I’ve tried using spreadsheets to track parts and projects, but never manage to keep things up to date. I think I need an AI buddy to help 
.
I must waste countless hours searching for parts that I know I have when starting new projects.
