External circuit to fpga

Hallo I'm newbie as user of FPGA DE0-nano. I want to ask, if connected external circuit to FPGA DE0-nano board, what must to be noted in order to FPGA board aware of destruction ? thank you ...

1. The DE0-nano pins are 3.3V and have no protection for over-voltage. Make sure you only connect 3.3V signals to the I/O headers.

2. Connect the ground on the DE0-nano to the ground on your external circuit so that you have a common reference ground.

3. If your external circuit is powered by the DE0-nano, then make sure not to violate the USB current draw.

Cheers,

Dave
