A basic circuit demonstrates how to to create a potential circuit with an ESP32 S3 microcontroller plus the 1k kiloohm impedance. Using placing pair of resistances in series, you can reduce a voltage amount into the http://theengineerstore.in/products/10w-15w-20w-stereo-bluetooth-amplifier-board-12v-24v-digital-power-amplifier-module-xy-p15w
