5W+5W Bluetooth 4.0 Stereo Amplifier Module

Compact dual-channel digital amplifier (65 × 45 × 15 mm, ~42 g) delivering 5W per channel into 4Ω loads. Features an integrated Bluetooth 4.0 receiver compliant with A2DP and AVRCP profiles — enabling playback control (play/pause/track skip) from connected devices. Powered by standard 18650 rechargeable cells, with terminals designed for direct connection to common UK-sourced battery holders. Built using robust PCB materials and selected surface-mount components to withstand vibration, temperature fluctuation and repeated connect/disconnect cycles. Wiring uses standard 0.1″ pitch screw terminals — compatible with UK-spec multistrand hook-up wire (e.g., RS Pro 0.5mm²).
