I just added the Gerber and Drill files to the Files area. These files are provided in the hope that they might be useful but completely "As Is". There is no warranty of any kind including correctness or suitability for any purpose. The Bill of Materials has Digikey part numbers that were current when I did this project. The chips should be readily available, the passives may have changed. There is nothing magic about the passive components, substitute like values, sizes and ratings, and they should be OK.
