I thought the KK mini had a connector on it that the buzzer plugs into?

It does but instead of putting a wire to that from my lipo im going put the wire to the obercraft cause it has a way louder better buzzer just dont know if I run it to the positive and leave the ground open or should I run the ground elsewhere cause obviously the spot on the kk has no ground for the buzer connection.

So whatever board you have already has some sort of circuit on it that allows a buzzer to go off indicating a low battery and you want to use the buzzer from the mini KK? I'm a tad bit confused.

It has a buzzer on the pdb but im suppose to wire from pdb positive and negative to say a naze32 positive and negative that is used for a lipo alarm but kk mini only has positive.

...then the PDB ground will be enough...the KK + pin for the board buzzer is all you'll need. KK will provide the signal when/where ever you set your Min Voltage alarm to sound at...

VBAT is for the PDB to FC voltage reading wire and buzzer is again, single wire with the PDB common ground.
...I don't remember if you said you will be running OSD (ON SCREEN DISPLAY) that is for VBAT/Heading/Altimiter if you run a different FC(PIXHAWK, ETC...)

I knew about osd and the buzzer but where would I hook vbat to kk mini? Or do I hook the positive on kk for reading voltage to somewhere that gets full lipo. Power and cut the kk buzzer off and wire those or it to vbat? O.k lets get basic. Theres a positive and neg. Vbat and positive and neg. Buzzer how do I connect them to kk mini?im slow sometimes

No problem...I don't have a KK Mini but saw the one photo in the post...looks like there is one red based pin saying BAT...this for the direct battery voltage reading for the KK to....the PDB in your case.
If this was on something without a PDB, You would tap battery voltage wherever is available like the closest ESC or harness you have created.

So what should I hook up to positive and negative on buzzer pads on pdb? So, red on the kk should go to vbat poso you think and leave the ground open? Im guessing it puts out flight voltage.the pdb has a buzzer speaker on it so maybe the voltage spot is to connect to a rx output to control by tx for lost model?
