Hi, I have the LS20031 GPS. I have a few questions:
First, if you have one, what condition did you receive yours in? The top of mine is significantly scratched/blemished.
When power is applied, the red led turns on for a bit and remains off (with no communications on RX/TX). Does this mean there is no GPS signal?
I am trying to use this with the through-hole RS232 shifter kit. I have everything on the breadboard, and a 78L33 voltage regulator provides the GPS with 3.3 volts. The RX light is pulsing continually and the TX light is dim. However, I get nothing on realterm.
Any ideas? Thanks!
EDIT: Looks like I never let it warm up enough. After typing this post the LED started blinking. I had to use an arduino without the mega168 as the converter, the sparkfun shifter did not work for me.
