FUBARINO SD CARD.v1.4- Help

hello,

  1. what do you want to ask?
  2. mind the fubarino board's pins are 3.3V input/output rated, some of them might be 5V tolerant..

that voltage regulator, used to power, all the circuit 7.4v/4A to 5V/4A?
¿I need some other component, among other components to work
right? =(

fubarino, WS2803D,SN54/74AHCT08, 4A resist me, not burned?
