What I have: a feniex T6 LED surface mount strobe light for emergency lighting. Flash patterns are selectable using an auxiliary ground wire. What I want: a pin out that the polarity can be changed by radio. I want to connect this auxiliary ground to this pin so I can cycle the flash patterns on command. Is this possible? I have read the Naza has an expansion slot. Can I use this or is there another/better place for what I'm looking for. The light is all ready attached to the bird and I have the flash pattern static.
