Read moreThe JHEMCU Smoke Stopper, equipped with a self-resetting fuse, helps prevent short circuits when power is first applied from the battery to the assembled quadcopter. With the Smoke Stopper, you can know exactly if there are serious over-polarization or soldering problems, without the potential loss and subsequent replacement of electronic components.
Compared to standard smoke stoppers, the JHEMCU offers much lower trigger and hold currents and faster response times. In addition, the JHEMCU offers a wide input voltage range and a choice of input/output connectors.
Note: We recommend that before applying power to the quadcopter, be sure to test the + and - pins with a multimeter to determine possible polarity reversal. By the time the fuse blows, something may be broken. It does not protect against all possible types of damage.
