Hey guys I have a 250zmr, and a 250qav I had 2 balance connection buzzer alarms that r great but how do I connect my fatshark fpv gear and the buzzer? They both power by the balance leads.. Can I buy something that will give me power to my buzzers? 3s batteries guys... Ty
 
Treyh sorry cant remember do you have the KK board if yes it has a built in voltage alarm just need the lead from the red power lead to the pos pin on the kk board , Let me know if this the FCB you have and I will send you link to how to wire up
 
Are you referring to putting a low voltage alarm on your ground station? If so then can you provide a link to what voltage sensor you are using?
 
I was thinking of putting a low voltage alarm on my quadcopter by balance connection... I couldn't connect the fatshark and the buzzer so I decided to buy some balance connector extentions and possibly solder a splitter to power my fatshark and plug into the buzzer
 
You could do that if the buzzer was made to do that, or you could pull main power from the battery and plug it into the KK{s voltage alarm. The KK{s voltage alarm is really accurate, and adjustable.
 
There are two pins on the KK2.1.5 board, they are under a red header by the buzzer. It says power, and is marked + & -
 
Treyh DONT connect to the neg the KK 2.1.5 only needs a power lead from the pos side of battery to the pos pin on the KK voltage sensor , If you connect the neg as well the KK will burn out , This is why the neg pin is cut short so you cant put a wire on it
