Re: GPS module won't run on battery

Guys, how do I know if my GPS module is working?

Hello,

I split this topic into a new one since the one you commented on is 5 years old.

I would recommend starting out with the initial tutorial: https://learn.tinycircuits.com/Sensors/GPS_TinyShield_Tutorial/ to see if you can view any data in the Serial Monitor of that Arduino IDE. Make sure your baud rate is correct in the serial monitor.

Let me know how that goes!

Hi....In my case, the DC-DC converter is appraised for 220mA and is giving 5.2 volts, which I am dropping down to 3.3v for the GPS with a controller. Dopey, I know, yet this is a proof of idea. At any rate, the GPS and Bluesmirf turn out great off of the battery. I even snared the LCD directly to the GPS and got coherent NMEA information, yet regardless of whether I attempt to control the PIC off of 5.2v or the 3.3 volts out of the controller, nothing but bad. Different parts keep on working, yet I get, best case scenario, a weird person consistently or two on the LCD out of the PIC. However, I plug in the breadboard power supply and everything is dandy. Any thoughts?
