DIY Make Your Own KK2 LED Alarm for KK2.0, KK2.1
When my KK2.1 multi-rotor board arrived from HobbyKing, I was disappointed when I realized it doesn't include a warning LED. So I decided to make my own and I'll show you how in this video. HobbyKing sells these, but it turns out you probably already have the things needed to make one yourself.
Note, make sure you connect your flight battery to the KK2 so that it can sense the voltage. The KK2.1 has a 2-pin header that you can connect a JST or servo connector to. The KK2.0 requires you solder leads onto the KK2 board itself.
