No.out of curiousity, what is the minimum voltage that i can use with the board.
The Mega328 chip which is the "brain" of the Uno will work at lower voltages but the Arduino Uno board is designed for 5V.
Plus...supercapacitors often have very low current output (amps). It might not be able to power a Mega328 chip even if you find a board which works at 2.3V.
