Early Prototyping

posted Aug 11, 2014, 2:31 PM by John Kha
After a couple of revisions the breakout board for the ADAU1442 is ordered along with generic breakout boards for the UDA1338H and ATMEGA 328 and all the chips, too. I elected to use a TQFP 32 breakout and the SMD version of that chip as that will allow me to use the entire capabilities, especially the extra I/O, of the actual chip I will put on the board. I use OSH Park to do my prototyping Fab, because they are quick and have great quality.

The breakout board can be ordered here: https://oshpark.com/shared_projects/YgXyR8oX.

I have also uploaded what I have so far of the Kicad EDA files to GitHub. 

Special thanks to Dave Jones at the EEVBlog for his explanation of how to hand solder-- and design boards for hand soldering -- those pesky heat sink pads.
