It’s challenging to actually buy a Raspberry Pi these days unfortunately. All the official resellers are out of stock of all the other models and resellers have these on eBay for 3-4x the list price. Maybe this one will be in stock for longer…

A Raspberry Pi requires unobtainium Broadcom silicon. A Raspberry Pico uses Raspberry silicon. They claim to have millions of dies in inventory.

The Picos, I believe, are readily available still.
