I have put together the Adafruit Mini Flash SFX Sound Board along with the TDA2030A Amplifier module onto a piece of Protoboard. Took me a little while to solder out the pins and Speaker connection screw terminal block so I could solder the pins onto the back of the board and add some more pins for where the speaker connections go. I relocated the original screw terminal block from the Amplifier board to just the right of the module on the Protoboard and then connected the two with some jumper wires.
Right now I am powering the Adafruit SFX board with a USB cable but I have some LM7805 power regulators on order so I can just wire in 12V and split a portion of that off to power the Adafruit board with the 5V output from the LN7805.
I also started to make my Optocoupler board for the Sound Effects that will be generated from the Space Matt buttons. Some of the sound effects will be generated from the Switch Pods and I will not need the DTMF request wire that I have worked into this board as the Switch Pods already send a DTMF tone request. But I figure just incase I ever re-purpose these little boards for something different in the future it might be a good idea to have the ability already on the little boards. Here is a diagram of how I have the Optocoupler board wired (above left). Some other buttons I may need to get a little tricky with using that 555 timer board to request the Monitor Activation Sound when I turn on the lower console buttons for either the GPS or LCD screen as they are latching buttons and the Adafruit SFX board just needs momentary connections to activate any of the sounds on the pins.
