PAM8403 Class D Audio Amplifier

Here is the FV-1 prototype setup.

Step 1: PAM8403 Class D Audio Amplifier

I folded a piece of aluminum to act as a chassis, then mounted my SPN1001-DEV development board on it. I built one of my dual opamp pc boards and added it as an interface between the guitar input and the digital board. The opamp board can add gain to the guitar signal if needed.
Also, the power jack that I added is configured with center-negative like most guitar fx power adapters (the SPN1001-DEV has the opposite polarity) so when I take the test board over to my pedalboard, any of the pedal power connections will work with it.
 
The power and signal jacks unplug from the development board in case I need to isolate it for some reason.
 
All that is left is to clean the front panel and stick on some labels.

    Custom onewheel pint x battery box. Excellent print and material build. Great customer service. Exact fitment for project. Will use for future projects
    Properly manufactured and good quality PCB, all the component placement was okay and properly soldered.
    Very impressed with the build quality. The fasteners fit like a glove into the threads and countersinks. The plate is even smoother than I expected. It does have visible milling marks (as expected)...
