    Attach a power supply? :) Are you measuring the right pins? Arduino pins are the inside ones.

    Then something is wrong with your board or you are not measuring correctly.
    Are you putting 1 measuring pen on pin gnd and 1 on 5V?

    Does your Neo boot? If you load the Arduino blink example does your led blink?

    If your Neo boots into Linux or android these pins always give power.
