Overview

DarwinFPV XT30/XT60 Smoke Stopper device for safer power-up during RC FPV drone builds and troubleshooting. It is designed for bench testing to help protect electronics from short circuits, reverse connection, or overload by cutting power quickly and providing audible/visual alerts.

Key Features

  • 20ms response: cuts power rapidly on short circuits, reverse connections, or overloads.
  • Audible/visual status alerts: built-in LED and buzzer.
    • Normal: Green ON, Buzzer OFF
    • Fault: Red FLASH, Buzzer ON
  • Dual-interface compatibility: XT30 & XT60 connectors; supports 1-6S batteries (input 3-33V).
  • Resettable PTC fuse: after clearing a fault, disconnect the battery and wait 10 seconds to reset (no one-time fuse replacement needed).
  • Compact for testing: pocket-sized for bench testing and repair work; can test motor operation at low currents.

Clear LED and buzzer alerts make it easy to confirm normal power-up or spot a wiring fault immediately.

Dual-interface XT30 and XT60 connectors supporting 1–6S (3–33V) batteries for FPV and RC setups

A 2-in-1 XT30/XT60 interface supports common 1–6S battery inputs for drones and other RC electronics.

Resettable PTC fuse smoke stopper design with auto-reset after disconnecting battery and waiting about 10 seconds

The resettable PTC fuse restores protection after a fault—disconnect power and wait briefly instead of replacing fuses.

Compact smoke stopper used for bench testing an FPV quad build with battery connected through the device

Pocket-size form factor fits easily into bench testing and repair work while checking motors at low current.
