Built around efficient Class D architecture, each module handles direct wireless streaming from smartphones or laptops via stable connections up to 10 meters, while also accepting wired sources through the integrated 3.5mm AUX jack. Operating safely on DC 3.7V–5V, these boards run directly from standard USB ports, power banks, or single-cell lithium batteries. This flexible low-voltage design removes the need for external adapters, solving the common headache of upgrading legacy speakers or powering portable custom builds without draining batteries or consuming excessive shelf space.\u003c\/p\u003e \u003ch2\u003eBenefits \u0026amp; Tips\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eStream Without Dongles:\u003c\/b\u003e Leverage native Bluetooth 5.0 pairing for lag-free music transmission across multiple devices.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eExtend Battery Life:\u003c\/b\u003e The board draws approximately 15mA in standby, preserving power storage between listening sessions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMatching Guidance:\u003c\/b\u003e For best clarity and minimal distortion, pair the amplifier with passive drivers rated between 4Ω and 8Ω, and use a regulated 5V USB supply to avoid volume dropouts under heavy load.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAmplifier Class: D\u003c\/li\u003e\n\u003cli\u003eBluetooth Version: 5.0\u003c\/li\u003e\n\u003cli\u003eOutput Power: 2 × 3W RMS\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 20Hz–20kHz\u003c\/li\u003e\n\u003cli\u003eSignal-to-Noise Ratio: \u0026gt;85dB\u003c\/li\u003e\n\u003cli\u003eTotal Harmonic Distortion: \u0026lt;0.1%\u003c\/li\u003e\n\u003cli\u003eOperating Voltage: DC 3.7V–5V (USB Standard)\u003c\/li\u003e\n\u003cli\u003eAudio Inputs: Bluetooth RF \u0026amp; 3.5mm AUX\u003c\/li\u003e\n\u003cli\u003eSupported Impedance: 4Ω–8Ω\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePackage includes:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTwo (2) × 2x3W Bluetooth 5.0 Amplifier Boards\u003c\/li\u003e\n\u003cli\u003eProtective black PC housing for each unit\u003c\/li\u003e\n\u003cli\u003eMounting screw set\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWarnings \u0026amp; Reminders\u003c\/h3\u003e\n\u003cp\u003eAlways double-check positive and negative terminal alignment before applying power to prevent reverse-polarity damage.
