Ultimate GPS Module not working

Post by MMouton »

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

Are the header pins on the Feather soldered on?

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.

Cool. So maybe something with either the breadboard or the jumper wires? Glad it was something simple simple though. Thanks for letting us know.
