Evan - the DigiSpark board will run fine at 3.3 Volts, in which case you do not need level shifters. I do recommend changing the clock setting to 8 MHz though. Still plenty fast enough for I2C communications.

Steve,
Can you point me to the documentation on how to set the clock speed?? It would also help to know how to bypass the 5 volt regulator on the board.
I call it a DigiSpark board, as that was the first board that I could get the sample program to run.? I had to change to the?
ATtiny85 (Micronucleus / DigiSpark) board to get the sketch from Ashhar Farhan to compile.
Here is a picture of the two ATTiny85 boards that I have.
