Voltage Drop Board
Voltage Drop Board
Here is my voltage drop board. When the 12v+ gets to the ROV, its dropped down on this board to 9v and 6v respectively. The 9 volts goes to power the Ardunio and the 6 volts goes to power the servos. I wanted less wires running back and forth, so this was my solution. Looks horrible but this is a prototype, and it works, and will use it until I can make a fancy one. The heat sink is over kill, I need to cut it down a bit to fit inside the hull. All the connections will goto a protoshield for the Ardunio. I'm making a lightboard to sit on bottom of this one to take care of the lighting wiring.

Re: Voltage Drop Board
You can feed +12v into the vin port on the Arduino no problem... You could skip the 9v all together.
Re: Voltage Drop Board
You absolutely right. I've just been using 9volts this whole time for testing and whatnot, so I figured I'd just stick with it.
