Arduino Mega R3 Precision DAC V1.0.5 based on the Analog Devices AD5754 precision DAC.
All components have been thoroughly documented within their properties to include vendor, vendor part number, and approximate cost.
An Arduino library for the Analog Devices DAC can be found on my DAC project website

This project uses the Analog Devices AD9951 DDS chip to create a NCO/VFO.
All components have been thoroughly documented within their properties to include vendor, vendor part number, and approximate cost.
A preliminary library for Arduino can be found at my VFO project website
