On the Arduino board the "ARDUINO SWITCH aka CARD 3" section has a short between the "SDA" pin and the "AREF" pin. Only this section has the short. the LEDS and ENCORDERS section do not have that. Is this by design or an error? I'm soldering the pins now and was checking for shorts.. I first thought I has solder bleed over from on pin to another. Upon testing the other PCB's I have they are the same .. The back of the Arduino mount PCB has these 2 pins connected. Can you confirm this is supposed to be like that?  Thank you. |

Hi again, it should be a mistake, they are not connected intentionally. Cut the track in the middle to disconnect them. |

I wonder if this could be the source of some activity that I'm seeing. When I program "rev" switch on the autopilot I get interference with com1 on the audio panel?

Dan, I had already soldered the header pins to the board but was able to sever the connection between the two pins with an X-acto knife. I did it by sliding the blade between the header and the board and went back and forth a few times. I then checked it with my multimeter and it no longer showed continuity. That was worth a try and it worked, as I didn't want to start soldering a new board.  Larry |
