ATmega328 Fuse Bit Setting for 3.3V Vcc

By default, ATmega328 used in Arduino (such as Uno or Duemilanove) operates under 5.0V. Sometimes though it is necessary to use 3.3V supply voltage to accommodate peripheral circuits that cannot tolerate 5.0V. Continue reading ‘ATmega328 Fuse Bit Setting for 3.3V Vcc’ »
