DarwinFPV XT30/XT60 Smoke Stopper

Summary

When building or troubleshooting RC FPV drones 🛠️, incorrect wiring, short circuits, or reversed polarity can trigger deadly current surges ⚡ that instantly destroy flight controllers, ESCs, motors, or even your PCB—costing you time, money, and safety risks.

The DarwinFPV Smoke Stopper is your essential safety net 🛡️! Designed for drone maintenance and bench testing, it uses ultra-fast response circuitry with audible/visual alerts 🚨 to catch 90%+ of short-circuit issues. Supporting 1-6S batteries 🔋 and dual XT30/XT60 interfaces 🔌, it eliminates component burnout, cuts repair costs, and keeps your builds safe.

Features

⚡ Ultra-fast 20ms response

Cuts power instantly on short circuits, reverse connections, or overloads to prevent component burnout. More efficient than a multimeter for troubleshooting.

💚🔴 Dual audible/visual alerts

Built-in LED and buzzer; Green light stays on (buzzer silent) in normal operation; red light flashes + buzzer sounds on short circuits/wiring errors. No extra tools needed—new pilots can quickly identify issues.

🔌 2-in-1 universal compatibility

2-in-1 XT30/XT60 design works with all FPV drones, UAVs, and RC cars, supporting 1-6S batteries to cover most mainstream setup needs.

🔄 Resettable PTC fuse

Uses a PTC resettable fuse (non-one-time use).After clearing a fault, disconnect the battery and wait 10 seconds to reset—reusable long-term, saving time and money.

🧳 Compact & portable

Pocket-sized and easy to carry, built for bench testing and repair scenarios. Can test motor operation at low currents—an essential safety accessory for drone setup.
