WS2812 LED Module Decoder Built-in Buzzer for Pixhawk / Pixhack / Pixraptor Flight Controller
LED Modul decoder which decodes the I²C control signals for the external LED and controls six of WS2812 LED.
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).
if placed too close to the flight controller which can lead to poor altitude hold performance when the buzzer is activated.
The buzzer should ideally be mounted at least 5cm away from the flight controller
and the speaker (i.e. the open hole) should not be pointing directly at the flight controller.
The WS2812 Led Strips need 5V.
Never power any amount of WS2812 Led Strip from the flight controller or the flight controller's power supply!
One WS2812 Led Strip can pull up to 60mA.
That accumulates pretty quickly into significant currents when using many.
