RSeries I2C is +5V vs NXP standard of 3v3 #4

RSeries I2C is +5V vs NXP standard of 3v3.

The NXP standard, like the NunChuck connector is 3v3 VDC.

However to power the I2C FX Modules, we used 5VDC so that one 4 wire cable can 
do both the I2C and the power to the other Arduino UNO.

Currently there is no plans to move this to 3v3 volts. If you need to interface 
a 3v3 I2C device, please consider using AdaFruit's $3.95 4-channel I2C-safe 
Bi-directional Logic Level Converter - BSS138,

This really brings to surface... can we move everything to 3v3 on the 
controller? It appears we could.
