Product overview
The iFlight Smart Smoke Stopper - XT90 limits current flow to help protect electronic components when a defective part or short is present during a quad drone’s first power-on. Designed for 2-8s quad drones, it has XT90 input and output connectors for use with XT90-equipped FPV drones. Its trip current is 1.2A. The LED glows green when current is within 1.2A; in an abnormal situation, the LED switches off and beeping begins.
The package contains one iFlight XT90 Smoke Stopper. It provides a way to troubleshoot electrical faults while helping protect components from current surges. Protection does not cover every wiring error; wiring should be checked with a multimeter before voltage is applied.
