**Key Features**

Bluetooth A2DP  Compatible with smartphones, tablets, and computers. Stream music wirelessly with low-latency and reliable connection.

32-bit I2S Conversion for PCM1754: Incoming 16-bit Bluetooth audio is internally converted to 32-bit and fed to the PCM1754, maximizing DAC performance and dynamic range.

PCM1754 DAC Output: Enjoy high-quality analog audio suitable for powered speakers, headphone amps, or hi-fi systems.

Low-Power Design with Auto-Off: Keeps power consumption minimal. The system can auto-shutdown after inactivity and supports manual power control via a button (2 sec. hold to shut it down).

Battery or External Power: Latching power design allows stable operation from Li-Ion or regulated supplies.

Single Li-Ion/LiPo battery charger with a maximal charge current of 500mA;

primary-side protection IC for single-cell Li-ion/Li-polymer batteries with OVP, UVP and Overcurrent/Short Circuit;

'Resistor-coded' USB-C 5V input used to charge the battery and/or to power up the board;
