They say you can hurt the chip in the JB4 but to me that makes doesn't make a lot of sense. Can't hurt it, would either just work or not work.
Idk :/
It requires a 5v TTL levelling cable with a custom pin out configuration. If you plug a standard 12v USB cable in you can sometimes fry the board. If you buy the cable at the same time with the JB4 new it's only $30.
