user34344: I am planning a build with my own enclosure for the arduino due. As an alternative i would like to bypass the power jack and usb port that are factory soldered onto the board, in order to use jacks mounted on the enclosure, along with a power switch.
I've looked at the info regarding the boards pin configuration at https://www.arduino.cc/en/pmwiki.php?n=Main/arduinoBoardDue, and would appreciate if someone could confirm or correct this:

Can i use an external 9V adapter through a jack connected to the Vin and GND pins, respectively?

According to This question, you can't connect an alternative programming USB port to Serial 0 TX/RX pins (Mega board). If this applies to the due as well, what do i need to break out the programming USB port?


Edit: Perhaps one of these puppies is the least complicated solution?

user54158: so 1 - yes. the VIN pin has a common trace with the barrel jack, you can verify with a multimeter in continuity/beep mode. ive actually put power out through the barrel jack on a mega.
2- i cant find a clear schematic for the due at the moment, but on the mega the rx/tx pins are also common with the usb pins, thus they are not usable while plugged into usb
