HI
i´m trying to burn some power control like sparkfun power driver on EAGLE,
I ended like this board, it seams everything ok???
i´m alredy printing on board, but i haven´t been sucessefull...
any tricks??
PEACE
EDIT : added schemantic
Looks OK, but I would add another ground terminal, then there is a GND and +12V
terminal for the power and a separate GND to go with the signals - you don't want
to run high currents down a signal ground wire.
Also where are the gate resistors?
i think gate resistor are those 3 resistors to each IRF right?
nice idea to separate GND, is to run 12v maximum...
Thank you
Draw:polygon around the outside perimeter of the board, and right-click and Name it GND.
Add it on Top & bottom layers.
Tools:Ratsnest to see the result.
Might have to wiggle the start/stop position a little after drawing for the polygon to close correctly.

They look like pulldowns to me.
I really hope whatever you put on there begins with "IRL", not "IRF"...
Where will you connect the Arduino GND? It would be nice to have a proper terminal for that.
Hi fungus, Thank You! for reply,
To understand, where should be connect resistor?
I really hope whatever you put on there begins with "IRL", not "IRF"...
is nor IRF 
Where will you connect the Arduino GND? It would be nice to have a proper terminal for that.
I´ll use, an extra transformer like
with 5V to arduino and 12V for this part, is ok right?
KJMM:
with 5V to arduino and 12V for this part, is ok right?
Yes, as long as all GND are connected together.
ok, was what i was thinking...
meanwhile, i tested the board and the output it seams to be the one i expected, let see tomorrow with other parts,
what is the difference betewen "pulldowns" resistors and "gate resistor" ??????
Thank You!
Pulldown is a resistor to keep it grounded and to prevent it floating.
Pullup is to Vs/High eg 5v via a resistor .
Gates have a small capacitance and a resistor simply keeps the gate low or you may find ghosts switching things on when they should be off.
