I have one of these for the M12+T. Yes it requires a higher voltage. There is a surface mount 7805V regulator on board so an input voltage of 9V or so is recommended (thats what is supplied by the plugpack that came with it). There is a 3V SMT regulator on board as well for the GPS receiver module.
