 * A compatible Arduino board @16MHz, I use an Arduino Pro Mini (must be powered by 3.3V!)
 * GameCube controller extension cord
 
-To my knowledge no 3.3V 16Mhz Arduino board exist, but the ATmega328p on a 5V 16Mhz Arduino Pro Mini can run at 3.3V. Though this is not advised to do so, I personally haven't had any issue doing so, but please keep this in mind. Additional information can be found in the microcontroller datasheet:
