3.3v 16MHz Arduino Comp. Pro Mini Board

Perfect choice for MultiWiiCopter boards.

You don't need an additional Logic Level Converter anymore for 3.3v I2C sensors.

These boards include 3.3v LDO voltage regulators for safe 3.3V applications.

And Atmega328's clock frequency is already 16Mhz for fast multicopter calculations.
