   In 2024, $.32 gets you a Cortex M0, 4kB RAM, 16kB flash and a built-in 24MHz oscillator. All in a package that's terrifyingly close to being accidentally swallowable.

     @obot50549535 This is surface mount (QFN; edit: actually DFN). You can just reflow it.

     If you're very bored (and hate yourself the exact right amount to do this without optical magnication), you can also dead bug it :).

     @q3k are you supposed to wire bond it? Or are those surface mount pads?
