DFRobot Super Capacitor 100F 2.7V - FIT0134 normally open and unlike the UNOSupercapacitor 100F 2. 7V Massive Energy Storage The 100F 2. 7V Supercapacitor stores an enormous amount of energy compared to regular capacitors enough to power a microcontroller for minutes or even hours after main power is removed. Supercapacitors (also called ultracapacitors) bridge the gap between batteries and capacitors: they charge in seconds, last millions of cycles, and discharge slowly.
