This is a trigger unit for Skycat parachute launchers. It's wired to the Drone radio battery (or supply your own small Lipo battery), and Skycat launcher unit.
The unit listens to a PWM signal from your Drone's radio, and upon command, transfers energy from a Drone battery or dedicated battery to the launcher. Two or more triggers are supported for redundancy.
The trigger is shipped with 15 cm receiver cable and 30 cm cables for parachute battery. XT60 connectors are not soldered, so you can adjust the wires for perfect fit. Base plate for attaching the trigger to the UAV frame is included.
