# Absolute Maximum Ratings
*Noted Voltage should be delivered only with current limitation under 2.5 Amp.
# Recommended operating conditions
|I max @ 30V||0.260||A|
# ESD ratings
|Human-body model (HBM)||2000||V|

Recommended mechanical mounting
There are no specific recommendations. However, in general the navigation lights should be placed at the very end of each wing and tail.
Connection example diagram
To display the status of the autopilot, this board should be connected to one of the autopilot's CAN ports.
Alternatively, this device can be connected to Sniffer and controlled manually from the GUI tool.
# Power Supply Recommendations
Device is designed to operate from an input voltage supply range between 4.5 V and 5.5 V over CAN1 connector, or 5.5 - 30 V from CAN2,3. This input supply must be able to withstand the maximum input current and maintain a stable voltage. The resistance of the input supply rail should be low enough that an input current transient does not cause a high enough drop that can cause a false UVLO fault triggering and system reset. The amount of bulk capacitance is not critical, but a 47-uF or 100-uF electrolytic capacitor is a typical choice.
