  TDA7498E Description The  TDA7498E   is a dual BTL class-D audio amplifier with a single  power supply  designed for home systems and active speaker applications. It comes in a 36-pin  PowerSSO  package with exposed pad up (EPU) to facilitate mounting a separate  heatsink . TPA3116D2 Description The  TPA3116D2  is a stereo efficient, digital amplifier power stage for driving speakers up to 100W / 2Ω in mono. The high efficiency of the  TPA3130D2   allows it to do 2 × 15 W without an external heat sink on a single layer  PCB . The  TPA3118D2   can even run 2 × 30 W / 8Ω without a heat sink on a dual-layer  PCB ,  If even higher power is needed the TPA3116D2 does 2 × 50 W / 4 Ωwith a small heatsink attached to its top side  PowerPAD . All three devices share the same footprint enabling a single  PCB   to be used across different power levels.

  ESP32 Description ESP32  is a series of low-cost, low-power systems on a  chip microcontroller  with integrated  Wi-Fi  and dual-mode Bluetooth. The  ESP32   series employs either a Tensilica  Xtensa LX6   microprocessor in both dual-core and single-core variations, or an  Xtensa LX7   dual-core microprocessor, or a single-core RISC-V  microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules.  ESP32   is created and developed by  Espressif Systems , a Shanghai-based Chinese company, and is manufactured by  TSMC   using its 40 nm process. It is a successor to the  ESP8266   microcontroller. STM32 Description STM32  is a family of microcontroller ICs based on the 32-bit RISC  ARM  Cortex-M3 3F ,  Cortex-M7F ,  Cortex-M4F , Cortex-M3,  Cortex-M0+ , and Cortex-M0 cores.  STMicroelectronics  licenses the ARM Processor IP from ARM Holdings. The ARM core designs have numerous configurable options, an
