The Broadcom chip, or the RPi system design, seems very sensitive to the least little bit of ESD or having an I/O pin shorted to ground. Those chips really were meant for the inside of a cell phone and not to have unprotected I/O brought out to a user header. Also, I don't have to add an external dongle for wired Ethernet. good to know. tho, i would not count on internals for shorts or actual esd. either human or lightning / switching. need external diode / tvs circuits or optical / magnetic isolation > >(Also, what less-than-stellar engineer thought up putting the 5V and 3.3V rails right next to each other on the expansion header without putting GND in-between them? One slip of a probe tip and poof, there goes your RPi.) oh don't worry, nanopi neo core, allwinner h3 i have, has same thing. i was wtf. in my custom extension ports i tried to get 5v as far as possible from 3.3v and additonally made it so when you accidentally reverse your, also 40pin, connector, you end up with things not quite working right, as opposed to blowing things up but rpi had own reasons for that i guess. now it stuck. now we're crapped > >--- Zach >
