9V Battery Adapter
The 9V battery module provides power to your circuit. It contains an on/off switch, allowing your circuit’s power to be controlled at the source. A blue LED indicates when the power is on, while a red LED indicates when the module is shorted. Battery included.
The 9V battery component provides power to your circuit. It contains an on/off switch, so power to your circuit can be controlled at the source. Turning off the battery module when you are not using it also helps you conserve the battery’s power. A blue LED indicates when the power is on, while a red LED indicates if the battery is shorted, at 250mA of current. In the event of a short circuit, its protective circuitry, composed of diodes, resistors and capacitors, ensures that the module does not blow. The battery adapter plug easily snaps onto a 9V battery when it is oriented in the correct direction.
