Hi!

We recently bought the VIFLY Finder V2 to help find drones in the event of a crash. However we are struggling to figure out how to connect it to the VOXL instead of connecting it to the receiver. Any ideas on this?

Best,

Rohit

This looks like PWM interface.  Are you using "VOXL" or "VOXL-Flight"?  VOXL Flight has PWM outputs, normally 4 are used for the ESCs, but the system can use the 'aux RC passthrough' as a means to trigger this signal.  Does the buzzer normally get triggered by the user or automatically via some logic?

We have the VOXL-Flight. The buzzer can be triggered automatically when the battery disconnects and by the user through the controller.

Hi @rohitpillai ,

Sorry I had this queued to send but didn't send it!

If it's VOXL-Flight, you have PWM outputs you might be able to use if you have a quad setup.

See [this](https://docs.modalai.com/voxl-m500-gimbal-user-guide/#aux-passthrough-rc-channel) as a possible option, where you can setup an RC channel (via the controller) to trigger the channel and possibly activate the buzzer (assuming it has a PWM interface).
