Bluetooth stereo moduleaudio transceiver brand new and high-quality Suitable for Bluetooth stereo audio transceiver and high-quality voice box Very low operating voltage Built-in lithium battery charging circuit Powerful noise cancellation circuit PCB LAYOUT NOTES: 1. Power supply decoupling capacitor shall close to module pinposition. 2. Module substratum shall full floored (must not floored underantenna) and insulation white oil paved on the substratum position. 3. All ground wires of audio circuit and module shall be separatedwith others' and full grounded in the power supply grounding location afterindependent routing. 4. All ground wires shall be paved of copper largely. 5. Module antenna shall be placed at the edge of the plate(extension better) and away from metals to ensure good communication withoutside.
