## Description

**ESP32 Hi-Fi Boombox: I2S Audio & Power Management Suite**

This isn't just another ESP32 breakout; it is a fully integrated audio engine featuring dual-channel I2S amplification, smart LED visualization, and a rock-solid power delivery system designed to squeeze every watt out of the MAX98357A.

**Technical Specifications**

* Processor	ESP32-WROOM Series (Integrated Bluetooth/Wi-Fi)
* Audio DAC/Amp	2x MAX98357A (Left & Right Channel separation)
* Output Power	3.2W at 4Ω / 1.8W at 8Ω (per channel)
* Power Input	USB-C with CC Resistor Coding (5V/3A negotiation)
* LED Peripherals	2x On-board Headers for WS2812B (8 LEDs per strip)
* Audio Protocol	Digital I2S for noise-free transmission

**Safety & Power Engineering**

To ensure your battery and speakers stay healthy, the circuit includes:
* OVP (Over-Voltage Protection): Shuts down the rail if a faulty charger is detected.
* UVP (Under-Voltage Protection): Prevents deep discharge of your Li-ion source.
* Reverse Polarity Protection: Because mistakes happen.
* Dedicated 5V Rail: Boosted and filtered to ensure the amps have the headroom they need for peak transients.

**Visuals: VU Metering Ready**

The board includes dual 3-pin headers specifically mapped for two 8-LED smart strips. Use the provided sample code to turn these into high-speed VU meters that react to the I2S stream in real-time
