Hi,

When testing the DAQ, although it was succesfully recognized at one instance, when I tried it in my notebook smoke came out of the L13 inductor. I only have 3 boards so I am a little worried about what happened to this one.

I checked the connections and everything seemed fine. I re-solder everything, and tried in another computer and everything seems to work... Except a small hole in the L13 inductor. As I am not really an expert in electronics I don´t know what the damage is, and I have no clue what is this inductor good for. I´ve got 3 LEDs lighted up, and the red one in the CMOS, and the computer recognizes the board. Nevertheless I have several problems and I would like to understand if I should try to fix this board or just try again with one of the 2 I have left.


1st. I can´t load the firmware in the EEPROM, everytime it fails to upload it. I can do it to the RAM succesfully and then the camera is recognized in the device manager.

2nd No frames are acquired. When I press connect it says frames are not being received. Also I don´t have control over the led intensity.

3rd The first time I connected the DAQ with the PCBs I had the LED light all the time turned ON, but eventually it started to flicker and now is barely illuminating.


I would normally just keep trying with the other boards, but I really wanted to understand first what is wrong, so I don´t break the other two. I would really appreciate if you could help me with this.

Best regards, Claudio.
