Anybody know the color code for the NAZA-M gps module?

The NAZA has 4 wires colored yellow, red, brown,and orange.

What is 5 volt, gnd, tx, and rcv lines.

Tough to find any documentation on the Internet.

Have a look in Wiki under GPS setup. https://librepilot.atlassian.net/wiki/spaces/LPDOC/pages/12058679/GPS+setup
Otherwise search Forum with NAZA GPS wiring.
good luck

This may save you some time:
+V = Red
-V (ground) = Brown
Tx = Yellow
Rx = Orange

However:  be careful if/when removing or replacing the DJI connector because it contains an insulating sealant that discolors the insulation on the individual wires.  I've modified some NAZA GPS units wherein the wire insulation has discolored, the yellow has turned green and the orange has turned yellow.  Peel back the outer (grey) insulation far enough to see the original colors.
