This basic setup shows the way for build an potential circuit using the ESP32 S3 module plus a 1k Ω resistance. By placing pair of impedances to order, one can lower an voltage amount for the value suitable for sensing http://theengineerstore.in/products/2-80w-100w-bluetooth-5-0-aptx-hd-tpa3116d2-power-amplifier-board-2-1-tpa3116-pcm5102a-dac-audio-ne5532-equalizer-class-d-amp
