I'm using a SX28 protoboard for a project that's going into a new Toyota Tundra.  My questions are--

Should I use a dc-dc converter to keep the voltage at the board a constant 12v?  (9v-18v in with 12v out {1.25amp} with internal isolation)  I'm not sure how the board will handle with voltages ranging from 10-14.6v.  

I'm going to leave the on/off switch in the on position with board being powered on through a switched ignition feed.  It should be o.k. for long term?

Should I use some type of protection on either the B+ or B- side?

Thanks!!

Greg
