PM sent, thank you very much

I made some tests with a phototransistor I have removed from a remote, Canon S110 LED blinks too fast for me to catch the Voltage on the meter
Be aware that the tuffwing Canon IR cable actually sends 3.3V and not 5V like I said before, my fault

It contains a phototransistor that acts as a switch that changes to a low impedance state when enough light enters it's lens (causing a base to emitter current that allows a much larger collector to emitter current to flow). So the three wires in the cable hook to +V, GND, and signal from the flight controller. I suspect it will work just as well with V=3.3V as it does with V=5V.
In this case, cable for log photo time, it is the module that sends an on or off signal to the pixhawk (signal) pin.

My point is that the module does not "source" any power - it simply switches a voltage that it gets from the flight controller back to the flight controller when the camera LED is illuminated. So the cable should work for flight controllers that use 3.3V or 5V.
I'm not an electronic expert but I can't buy from USA right now so I have to try to make this cable by myself
Can you point me to a script that leaves the S110 LED ON?
