Hello,
I've just received my Ultimate GPS breakout and I've been wanting to wire it to a ESP32. The FIX LED should be blinking at 1Hz while looking for a fix but there is no light at all and I get nothing in the serial monitor. Is it possible that the module is simply defective ? I'm pretty sure that I've done the correct wiring

Re: Ultimate GPS Module not working
Are the header pins on the Feather soldered on?

Re: Ultimate GPS Module not working
Hmm. Weird. Yah, you should get a blinking LED with just power. Can you try jumpering the power connections more directly instead of via the breadboard power rail. You can disconnect the TX/RX lines if you want, since we are just trying to check basic power.
If you have a multimeter, would also be good to make sure there is 3.3V showing up on the GPS's VIN pin.

Re: Ultimate GPS Module not working
Cool. So maybe something with either the breadboard or the jumper wires? Glad it was something simple simple though. Thanks for letting us know.
