I want to connect 1 led to my matek h743. I use s6 pin and ground. and When I toggle switch relay 4 or any other relays nothing happens.
- I SET SERVO 6 to -1 as GPIO.
I want to control over x volt like on/off switch. I there any better way?
How you connect what kind of LED exactly?
Did you read the GPIO-wiki GPIOs โ Copter documentation?
The GPIOs are only logic level in/outputs. โ12 volt ledโ donโt seems to be logic level.
How you control your โServo 6โ output?
1-)just standart led strip
2-) No I havent I will
3-) Okey
4-) via mission planner
If you just give so short information it is not easy to help.
A standard led strip will never work in this kind. You need a kind of driver in between.
so is there any like give 12 Volt to pin with demand?
First give some more details about your LED strip. Do you have a datasheet, a more detailed description or at least product label.
In principle you can use a simple tranistor with open collector to do the job.
Bottom line itโs 3.3V from that output. Figure it out.
the Vsw pad can switch Vbat or 5v output.

You could use the 3.3V signal from the GPIO to trigger a solid state relay (SSR) that could then control the 12V with the current needed for your LED strip. Look for a DC โ DC SSR.
