I would like to do this project (https://learn.adafru.../rgb-led-strips) using a Netduino Plus 2 and was wondering about power. My power supply would be a 12VDC 12AH lead acid (scooter/lawnmower) battery. If I want to power up to 4A worth of 12V led lights, would it be ok to use the barrel connector and the Vin/Gnd pins on the Netduino, or should I use an external transformer to covert to USB, then use that to power the Netduino and connect the LED strip directly to the battery? I searched the forums as best I could to find this answer, but couldn't determine if max power draw included the Vin/Gnd pass through, or only what was being passed through the control pins.
I am new to the Netduino and any help is greatly appreciated!
