No serial output for AdaFruit Ultimate GPS breakout

Post by baude »

Looking for any tips here, but I bought a an Adafruit Ultimate GPS breakout and I am unable to observe any output from the GPS via serial. I have tested two different cables and same behaviour is observed. To check for output, I am doing the following:

cat /dev/ttyUSB0

I'm certain of the device and one of the cables has been used with another project so I am certain it works.

In terms of checking resistance, should each of the four pinouts be completely isolated? Other ideas for debugging?

How are you connecting the breakout to your computer? What are you using on the computer to receive the data?

Any ideas? On the advice of a colleague, I checked the voltage in and it was in fact 5V.

Post a photo showing your hardware and connections and we'll take a look. 800x600 images usually work best.

With the connections please. We need to see how you have it hooked up to see if there are any problems there.

So it looks like the "ring"--where you solder--of the TX connection is not present. I am not sure if it was that way or was damaged by me. But that clearly explains the issue. Advice on what to do?

You could try scraping off some of the solder mask and solder a wire to that or trace back to the nearest point you can access. Post a picture so we can see if there are other options.
