Today I soldered the header pins to the sockets of the MCP4725 Digital to Analog Converter (DAC) board. This board will generate analog drive signals in the range of 0-5 VDC from digital signals sent to it over a I2C communication link from the microcontroller board. The drive signals will further be fed to a bipolar amplifier circuit, serving as the final set of signals controlling the position of the galvonometer mirror. As a reminder, the galvonometer mirror is what creates the fan of beams from the original single laser source.
