It supports Bluetooth 4.1 and earlier versions, enabling wireless audio streaming from most modern mobile devices. On the output side, it works with any external amplifier, home audio system, or car audio setup that accepts a stereo audio input.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do I need an amplifier to use this board?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — this board does not include a built-in amplifier. It outputs a line-level stereo audio signal, so you will need to connect it to an external amplifier or powered speaker system to hear audio. There is no limitation on the size or type of external amplifier you can use.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I power this Bluetooth receiver module?\u003c\/h4\u003e\n\u003cp\u003eA: The board can be powered in two ways: via a standard Micro USB port (using a regular Android-style data\/charge cable) or through the 2.54mm pin header with a DC 3.7–5V supply. This makes it easy to power from a USB wall adapter, power bank, or directly from your existing circuit board.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I embed this module into my own DIY audio project?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The ultra-compact size (3.3 × 3.5 × 1.1 cm) and 2.54mm pitch pin headers are specifically designed for DIY embedding and soldering onto custom circuit boards. The high-fidelity output circuit with RC isolation ensures clean, noise-free audio in any custom build.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What devices is this Bluetooth audio receiver board compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This Bluetooth audio receiver board is compatible with Android and Apple (iOS) smartphones and tablets.
