Adafruit Mini SFX Board With TDA2030A Amp. Module UPDATE

I combined the Optocouplers board for the button inputs for my Space Matt buttons by soldering it onto the other piece of Protoboard that I had already attached the Adafruit SFX mini and TDA2030A Mini Amplifier boards onto. I soldered the inputs for the Optocouplers to 3mm screw terminal blocks to make connecting the wires from my Space Matt buttons easier later on when I install this module into my K.I.T.T.

There are a few things left to do like add in the power regulator to convert 12V into 5V for the Adafruit board, right now I just have one 100 uF Capacitor soldered onto the board seeing how I had it on hand, I still need to add a 10 uF Cap. and a small ceramic 100 nF cap to go with the power regulator but those are minor details that just basically involve waiting for them to arrive in the mail. Now the Optocoupler board you see mounted onto my main board also sends a pulse for the DTMF tone request on the Voice Box through a wire that will be connected to the screw terminal block mounted on the lower right side of the board (above left). I have four more sound effects options that do not require a pulse to be sent to the DTMF because they will be wired to the Switch Pod buttons and they already have a tone request being sent from the Switch Pod buttons. So I'll see if I can squeeze in four more Optocouplers onto the board somewhere for those loose green wires you see sticking out of the left side of the main board next to the Adafruit module and see if I can also squeeze in two more 3mm screw terminal blocks, it's going to be tight but I think I can do it, if not then I'll just have to add in another side board with the Optocouplers on it.

In the meantime to make things easier for me to install this module when completed I worked out a diagram to illustrate where all the pin outs are located on the module (right). It's coming together though just a few more things to do and then I can wire it up for a test in the car before seeing about perhaps stuffing this into an enclosure to make for a nice install.

Adafruit SFX Mini Flash Sound Board with TDA2030A Amplifier Module

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.
