On the AGX board, serial ports A&B are normally RS-232 levels, but the manual indicates that there is a factory option to have them at 3.3V levels. We'd like to do this, but of course, we'd also like to prototype our system this way first.
Understanding that we would accept responsibility for any damage that occurs, can you guide us as to how we might field-modify our existing development boards in a similar fashion? We have SMT workstations in-house.
