Great Jawa Horde Sound System Board v6 (Apr 2025)

This board provides the basis for a Sound System Enabled Jawa Mask.  It is essentially a mother board for one or two 433Mhz 4channel remote control receivers, an adafruit mini fx sound board and a 5v amplifier.  The on-board components are a pair of inverter chips to make the active-high signals on the receivers correctly trigger the active-low pins on the sound board, an largish capacitor to help isolate the amplifier from possible electrical noise from the fans, and some pull-down resistors so that we don't receive spurious triggers if the 2nd remote control receiver isn't installed.
