This is an experimental attempt to add volume adjustment function to M5 Stack. This is a SPK& module in order to avoid adding as much as possible inside M5 Stack Core. Please refer to the schematic of M5 Stack core and find and confirm how to disable AMP.(NS4150) inside M5 Stack core. The parts, circuits, and circuit constants shown in the photo may not necessarily be the ideal correctness. Even if M5 Stack and peripheral devices are damaged by this thing, I can not take responsibility for it. If you try this, please check the selection of parts and circuits at your own risk.
