The Avionics Anonymous Light Controller is a 4-channel light controller for unmanned vehicles. Each channel can be configured as a nav, strobe, beacon or landing light and can be programmed for various patterns. When connected to an autopilot running PX4, lights are automatically controlled based on the state of the autopilot! For example, beacons can be set to turn on when the system is prearmed and strobes to turn on when the system is armed, while nav lights may always be on. All of this is configurable via PX4 and UAVCAN parameters. The device interfaces to your autopilot via robust UAVCAN interface - much easier than trying to tune a PWM signal to give you the desired patterns using typical R/C light controllers.
What makes it special?
Designed for drop-in use with uniLight LED products
Supports up to 30V lighting voltage
Supports common-anode lights (combined lights that use the same power pin for multiple LED's)
4 separately-controllable channels supporting 3A each with a total limit of 10A.
3x connectors for 2 channels, 2x connectors for the other 2 channels means you can plug in multiple lights without having to splice
Robust UAVCAN interface is compatible with most Pixhawks and similar autopilots
Mount with screws through mounting holes
Update firmware via CAN interface
Weight: XX grams
Size: XXin x XXin x XXin
Power: 4.0V to 5.5V, XXmA
CAN Harness - connects between the autopilot and a CAN node and between each CAN node on the bus
The Light Controller includes 4x screw holes for 4-40/M3 screws. Consider using standoffs or otherwise spacing the board off of flat surfaces to protect the pins which protrude through the bottom side.
PX4 (Support coming soon)
Several autopilot parameters must be set using QGC or similar:
UAVCAN must be enabled by setting UAVCAN_ENABLE non zero. Set this to 1 for basic functionality or 2 to allow the device's UAVCAN parameters to be accessed via QGC.
Set the operating mode for each light using the parameters UAVCAN_LGT_ANTCL, UAVCAN_LGT_STROB, UAVCAN_LGT_NAV, and UAVCAN_LGT_LAND, as follows:
Lights never on
Lights on when system is armed
Lights on when system is prearmed (safety switch "unsafe")
Lights always on
The Light Controller node has a number of parameters accessible via the UAVCAN interface. These may be set following the steps outlined here
Node ID for this device
UAVCAN "SingleLightCommand" "light_id" value for channel 1
LIGHT_ID_RIGHT_OF_WAY (nav lights)
UAVCAN "SingleLightCommand" "light_id" value for channel 2
UAVCAN "SingleLightCommand" "light_id" value for channel 3
UAVCAN "SingleLightCommand" "light_id" value for channel 4
Pattern for channel 1. See "Patterns" table below.
5 (always on)
Pattern for channel 2. See "Patterns" table below.
1 (strobe, double flash)
Pattern for channel 3. See "Patterns" table below.
5 (always on)
Pattern for channel 4. See "Patterns" table below.
3 (beacon, single-flash)
Lights off, regardless of command signal from autopilot
Double flash at 1Hz
Strobe, double flash, but low-intensity constant light when not strobing
