{% hint style="info" %}
?V\_PAYLOAD rail can be used for custom usage. Supply for that rail can be created on a custom PDB and can be used on a custom adapter/reduction board.
{% endhint %}

{% hint style="warning" %}
Input supply voltage range is 9-26.5V (6S)
{% endhint %}

### Power consumption <a href="#power-consumption" id="power-consumption"></a>

### LED Channels <a href="#led-channels" id="led-channels"></a>

* supports WS2812 PWM communication protocol (WS2812 is used as reference, but there are more types of PWM LEDs with similar communication protocol. Compare datasheets for communication protocol compatibility )
* possible to connect up to 50 LEDs in the sum of all channels
* FRONT L, FRONT R, BACK L and BACK R are set to support a maximum of 10 LEDs per channel
* FRONT L, FRONT R, BACK L and BACK R channels can be controlled with predefined effects
* LED effects can be controlled from the Jetson driver through I2C

{% hint style="info" %}
LED control functions are implemented in the **Python LED control example**. **Custom effects** are controlled from Jetson. Python example can be found here: <https://gitlab.com/airvolute_oss/dronecore.os/dronecore.samples/av-led-control-example>
