External LEDsΒΆ

An external LED (aka “Toshiba LED”) can be added by connecting it to the flight controller’s I2C port. Because most users use a Ublox GPS and Compass module, an I2C splitter is recommended. If using a Pixhawk flight controller, once connected the LED on the center of the board may no longer light up (recent versions of ArduPilot will light up both LEDs).

The brightness of the LED can be controlled by modifying the NTF_LED_BRIGHT
