Tips and questions relating to the GPS modules from SFE
By jneice

I'm having trouble with the ET-102/ER-102 GPS RECEIVER ENGINE BOARD.

I use 5V DC on the unit and get no output from the TX pin.

I think it may have to do with the pin connections. I am only using pins 2 (VDC), 10 (GND), and 11 (TX).

On page 6 of the datasheet the pin diagram is shown, but the pin numbers aren't labeled! I was assuming pin 1 was the bottom right pin, counted vertically to 10, then the top left was 11, and the bottom left was 20. Is that correct?

Are there any other caveats with this unit? I thought it was as simple as powering it up an hooking it to a UART...

Thanks in advance!
