Overview
AD9850 is an open-source printed circuit board by grtyvr, from the grtyvr/AD9850_v1.0 repository on GitHub. It is a 2-layer board of 99.1 × 88.9 mm with 29 parts on 45 nets, routed with 201 tracks and 2 vias.
It is built around the ATMEGA328P-PU. Its parts include 7 capacitors, 6 connectors, 4 ICs, 3 switches and 1 resistor. It belongs with the AVR (ATmega, ATtiny) boards of this library.

Larger version of the board for the SigGen project: 328p based AD9850 function generator.
It is based on the project:
http://www.vwlowen.co.uk/arduino/AD9850-waveform-generator/AD9850-waveform-generator.htm
Which in turn is based on AD9851 code from Andrew Smallbone - modified for AD9850 http://www.rocketnumbernine.com/2011/10/25/programming-the-ad9851-dds-synthesizer
I have created the KiCad files for a board for this project. This version takes out the 100K current limiting resistor for the display led (on is on the board already). And it is powered not by a power jack but by pin header from a seperate power supply in the same case.

Questions
How big is the AD9850 PCB?
It measures 99.1 × 88.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AD9850 use?
29 parts, built around the ATMEGA328P-PU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the AD9850 KiCad files?
From the grtyvr/AD9850_v1.0 repository on GitHub, at the commit this page was made from: the board is AD9850.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AD9850 design in my own project?
Its repository states no licence, so its author keeps all rights: ask grtyvr before reusing the design.
