TW100U 100W Mono Bluetooth 5.3 Amplifier Board, TPA3116D2 Digital Power Amp Module, Support TWS Wireless Pairing, AUX/USB/Bluetooth Input, DC 12-24V Single Channel Audio Component for DIY Speakers

[True Wireless Stereo (TWS) Pairing] Take your DIY projects to the next level with TWS support. You can easily pair two TW100U boards wirelessly to create a professional-grade stereo system. No complex wiring is needed to achieve high-fidelity wireless audio separation. [Built-in Voltage Boost Technology] Unlike standard amplifier boards, the TW100U features an integrated step-up circuit that can boost input voltage to 19V or 24V. This ensures the TPA3116D2 chip always runs at its full potential for maximum loudness and clarity. [Supports Multiple Input Modes] Enjoy ultimate flexibility with three input modes: Bluetooth 5.0, AUX, and USB Flash Drive. Whether you want to stream music from your phone, connect a PC, or play lossless files directly from a USB stick, this board handles it all seamlessly. [Low Distortion & Precision Audio] Featuring the TPA3116D2 digital power IC, this board achieves a total harmonic distortion (THD) of less than 0.1 % even at high power. The chip integrates internal AM avoidance and short-circuit protection, providing a secure and reliable heart for your high-performance mono audio setup. [Wide Voltage Range & Reliable Protection] Designed for long-lasting performance, it supports a wide DC 12-24V input range. To ensure reliability, it is equipped with comprehensive protection against over-voltage, under-voltage, overheating, and short circuits, keeping your DIY audio projects safe and stable
