Bluetooth 4.0 5W Stereo Amplifier Board

Precision-built dual-channel amplifier board (65 × 45 × 15 mm, 42 g) with integrated Bluetooth 4.0 receiver and 5W+5W output capability into 4Ω speakers. Accepts standard 18650 lithium-ion cells for portable operation — cells mount externally, allowing quick swap or charging outside the enclosure. Constructed using low-noise op-amps, high-efficiency Class-D output stages and carefully routed signal paths to suppress EMI and preserve dynamic range. Terminal layout follows intuitive left-to-right signal flow: battery input → Bluetooth antenna → input selection → speaker outputs. Acts as a complete front-end for stereo speaker projects — receives compressed AAC/SBC audio over Bluetooth, processes it digitally, then drives passive speakers directly. Fully interoperable with UK-purchased Bluetooth sources including Apple AirPods-compatible transmitters, Android media players and Windows laptops with built-in Bluetooth stacks. Battery interface supports both single-cell (3.7V) and two-cell series (7.4V) configurations depending on desired output headroom and efficiency trade-offs. Used across diverse applications: compact garden speakers powered by solar-charged 18650s; retrofit kits for school drama department PA systems; modular audio nodes in maker-space installations; and lightweight sound reinforcement for UK craft fairs or farmers’ markets where mobility and rapid deployment are essential.
