A basic circuit shows how to for form one voltage circuit by the ESP32 S3 processor & one 1k Ω resistance. Using placing dual impedances on order, one can reduce an potential level into a value suitable to input to an http://theengineerstore.in/products/10w-15w-20w-stereo-bluetooth-amplifier-board-12v-24v-digital-power-amplifier-module-xy-p15w
