I have a little SIP breakout board with a BMP280 on it. I got tired of checking the datasheet every time I wanted to wire it up in a circuit so I made a little label for it and stuck it on the board.
Unfortunately I mislabeled it, reversing VCC and GND on the label. It obviously didn’t work when I tried it this way. But what surprised me was that it still worked when I corrected my mistake. According to the datasheet I exceed the maximum voltage (max=VCC+0.3V) on several of the pins.
Why didn’t it blow up?
