CIRCUIT SCRIBE Circuit Scribe Power ModuleThis power module holds a coin cell battery and outputs 5 volts to your circuit. Try using this coin cell battery circuit module to make refrigerator art since you won't have a heavy battery hanging off the side of your circuit. Note: this circuit battery module will power all of our other modules except the Fan and the Motor With Wheel modules (those require the 9V Battery Adapter or the USB Adapter).
