is it possible to light a 12v led from the udoo board without the use of relays?
No, you need a level shifter or an RGB led amplifier: http://www.amazon.com/LEDwholesalers-Repeater-Amplifier-LED-Strips/dp/B0040FPCXG
Too old to dig up but anyway, you can use a MOSFET or ULN2803. The max current is only 500mA for ULN2803, but you can piggyback it.
Separate names with a comma.
