Hi, Does the Uno frequency drop when you use the 3.3V rail instead of the 5V and can this be compensated for by introducing an increased delay in a sketch? So if the Uno is 16 Mhz at 5V then at 3.3V we have ABOUT 10MHz so should I double SAY any clock critical delays?? Best

Many thanks for your link Nick, all very very interesting.
