The device uses the MCP4725, a single-channel 6-bit digital-to-analog converter with an I2C-compatible serial interface. It does not have built-in EEPROM memory that would allow DAC register and configuration bit values to be stored when the power is off. It is recommended to use an Arduino (or a compatible board such as Dasduino) to realize the full potential of this device.
