12V LED Switch on Taranis


Hello ... i try a new quadrocopter frame named ENZO250 and in this frame you have 2 holes for 1,5W LED to light out all in front. Sounds nice. As the package arrived i think the first time about the energie of this led. Now my problem if i connect this directly to the lipo i lost too much energy i think. My FLIGHTCONTROLLER can switch a 5v LED ..

Now i have following idea.. i want to take the control signal from my fc led pin to trigger a npn to activate the led like in THIS EXAMPLE:

Im new at electronic ^^ and sorry for my bad english

hope you can help

greetings from austria

Leds help with orientation too.
2 leds is 3W. At 12V that is 0.25A. Compared to most motor currents you can ignore that.
Using a transistor for switching is common, yes

consult descriiption of your FC, and then it depends on what you want the LEDs to do.
