The Pixhawk passive buzzer has a JST-SH connector for direct connection to the Pixhawk flight controller. Once connected, it gives clear audio alerts and distinct tones that show flight modes and system statuses, so you get reliable feedback while you operate.
The Pixhawk flight controller E-switch module gives a convenient way to arm and disarm the flight controller instantly. It uses a three-position JST-SH connector and has a red light indicator, which improves the safety and usability of a Pixhawk-based system.
The set is compatible with the official 3DR version, and includes the switch and the buzzer.
Passive buzzer: distinct tones for flight modes and system status.
E-switch with red light indicator: arm and disarm instantly.
250mm switch length: easy installation.
8mm switch mounting hole: fits a standard panel hole.
3DR-compatible: for the official Pixhawk version.
About 50dB: a clear tone at close range.
A Pixhawk flight controller uses tones to tell you what it is doing: start-up, GPS lock, arming, low battery and failsafe each have their own sound. Because you often cannot see the board on a built aircraft, the buzzer is the fastest way to know the state of the system.
The safety switch is a hardware button that has to be pressed before the motors can be armed. That prevents accidental arming: the aircraft cannot spin up until you press and hold the switch, and the LED shows the safety state.
Mount the switch where you can reach it easily but where it cannot be pressed by accident, and place the buzzer where the sound is not muffled by the frame or a canopy.
