is Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz updates - Version 3 compactible with udoo neo if yes then how to connect?
Yes you can, you have to connect the TX/RX pins to pin 0 and 1 on the Arduino side of the Neo and use serial0 in the sketch. Serial0 is already available on pin 0 and 1 so if the example sketch declares a serial connection you can delete that part.
