Audio/RAM/Wifi add-on for the RX Breakout board, with Ogg/Vorbis demo

As a follow-on to my MP3 demo software, I decided to do an Ogg/Vorbis demo as well.  However, Vorbis needs more RAM than the RX chip has, so I needed a board that had RAM, audio in/out, and redpine.  Despite the plethora of RX boards I had, none had all three, so I made a new one just for this project.  Hardware and software files are here:

I still have plenty of the bare breakout boards, and if there's sufficient interest I can make a batch of these too.
