I am using a Pi in a fairly rough industrial environment. While the board itself is protected (physically), the sensors (some analog VDC and some I2C) are out in the "real" world. At times the sensors or the connections to them have been subjected to damage, including shorting of the Vcc voltage supply lines to GND or to signal lines leading to more than one fried Pi.
I was thinking of putting some very low current fuses on the Vcc supply lines, but thought I'd check here on strategies for board protection in this type environment.
Any insight greatly appreciated.
