Wow this is a ridiculous amount of information. Great work author. I see people commenting this is pretty old, but still great work and still pertinent.
Guy does months of work assembling a ton of info and analysis, the page scrolls for days, and the first comment is gee couldn't you include purchase links for my extra convenience?
Extensive writeup of all the pro's & cons of various parts/families. And a nice guide on what to look for when selecting a part.
But ~7y is a long time in electronics world.
Eg. RP2040 is missing from this article. Dual core Cortex-M0+ @133MHz & loads of peripherals. Last I checked €0.89/pc in small quantities.
Also many software issues may have been ironed out in the meanwhile. Or some of the mentioned parts disappeared from the market.
