Arduino board size

I have an Arduino Uno R3 that I am using for lighting a series of LEDs in sequence. I have discovered that the board is physically a bit (a lot) large for fitting into my application. is there a smaller Arduino unit that I could use for this?

The classic Nano (not to be confused with any other board with Nano in its name) will run the same code and has the same pinout as the Uno
