Hello!

Is on the BBB a reverse protection on the 5V plug (not the USB port)?
And what happen when someone put 12V or 24V on it?

Thank you!

No reverse protection. Apply 12V or 24V when the label says 5V, well, bye bye board.

Hi Gerald,

ok, thank you!

Actually not. Tps65217 has an internal protection for up to 20V on the AC pin. LDO can accept it also as far as I remember.

True. But it blows up the power control switch on the USB port. And 24V is over 20V.
