Seeking a DMX trigger MP3 player. I am familiar with the Fright Ideas BooTunes MP3 Player, but at $129 it seems a bit expensive.

At ~$30, this MP3 Module seems like a good price but I am not exactly sure how to wire this to DMX. Do I use something like this TTL to RS485 Adapter Module?

I am handy but could a little guidance from someone who has knowledge. Not exactly sure if this is correct or how to wire it.

For this to work I believe you will need to find an mp3 board that accepts commands via a UART (ie., RS232). The board you link to does support this however, this one does. This board has been around for awhile and is made by different companies but they are all essentially the same. If you want documentation just google "DF Player Instructions". If you go this route then you would need to connect the RX line on the mp3 player to the TX line on your converter and the TX line in the mp3 board to the RX line in your converter. I have never used RS485 so I cannot tell you how to send a command that is compatible with what the mp3 board is expecting but I assume it can be done.

This is really helpful. And if I needed a line out I would probably use something like this one or maybe even this one.

When I google "DF Player Instructions", all of them show the MP3 with an Arduino I probably need an Arduino Nano or Uno for control, right?

I would prefer not to get into programming Arduino if I can avoid it.

1) Yes - theoretically you could use any mp3 player that supports communication via UART
2) You would not need an Arduino board - your DMX controller would be sending the commands to the mp3 board to tell it to play. But again, I have not done this so I am just guessing at this point. Maybe a poster with experience with DMX controllers could chime in here?

You could use any serial controlled audio module (like the DF Mini Player) but to control with DMX you would also need an Arduino (or some micro controller) that would listen to the DMX stream and send the required serial commands to the audio module. The sound module requires specific serial commands and will not understand the DMX signalling.

There are lots of examples of DMX code for an Arduino but I haven't seen anything specifically to do this...
