I just acquired this module and have a Newbie question regarding the connections to an Arduino Nano powered by the 5V USB bus. I assume I can use the 3.3V out from the Nano as the power rail for the sensor. My question is will I able to use the module with the default SCL / SDA pins which might be operating at 5V ?
As long as you’re powering the AS7265X board with 3.3 volts and you don’t have any other 5 volt I2C devices on the same bus you will be fine running these off a 5 volt board. 
Thank you for responding so quickly !
One more question…I added the second line of code to show the wavelengths from the 'Read Banana ’ example. I just wanted to verify if these assignments are correct (i.e, wavelength A = 410, etc.)
Serial.println(“A,B,C,D,E,F,G,H,I,J,K,L,R,S,T,U,V,W”);
Serial.println(“410,435,460,485,510,535,560,585,610,645,680,705,730,760,810,860,900,940”);
If that matches the chart in the hookup guide it would be correct.
