QLG1 Gps Receiver module


 

¿ªÔÆÌåÓý

I am having problems with my GPS QLG1 module. When connected I have the red and yellow LED on solid. Never see the green.

IC2 has 5vdc on pin 3 and no voltage on pin 1 & 2, also extremely hot.

Should I assume a bad LM317LZ or could there be another problem?

If it is a bad voltage regulator is the part available

Thanks for any info,

John? KF4HRY

John,

A hot regulator with no output usually means that the output is shorted to ground.
Check C24 is the correct way round. Check for solder across tracks.
