Why does…? #23: why does a USB-C plug fit both ways?

Why does USB-C fit both ways… but old USB never did? 🔌🔄

🔌 Old USB-A: one row of 4 pins on ONE side of a little plastic tongue — so it only fits one way (and somehow it's always the wrong way first 😅).
✨ USB-C: 24 pins in TWO rows of 12 — and the bottom row is the top row turned round.
⚡ Power and ground sit on both rows, so flipped or not, it's still connected.
🤔 But how does the data know which way it went in?
🟡 A tiny sense pin (called CC)! The cable connects only one of the two, so the phone or charger can tell how you plugged it in.
🔀 Then a small switch chip routes the fast data lanes the right way — automatically.
