The board's single biggest draw is its combination of Bluetooth 5.0 connectivity and a selectable 3.5mm AUX input, which makes it easy to switch between wireless and wired sources; our review found the wireless link stable and the AUX jack automatically disables Bluetooth when a plug is inserted, simplifying setup for a workbench or small enclosure.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth 5.0:\u003c\/strong\u003e Provides a stable wireless connection for streaming audio from phones and other Bluetooth sources with lower dropouts than older modules.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3.5mm AUX input:\u003c\/strong\u003e Automatically switches to wired input when a plug is detected so you can use the board with non-Bluetooth sources without manual toggles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3POUT terminal:\u003c\/strong\u003e A three-pin output lets you access left, right and ground separately for flexible wiring to external amplifier sections or speaker terminals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide supply range:\u003c\/strong\u003e Runs on 3.7V to 5V DC so it can be powered from common USB power banks or small battery setups for portable projects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrue stereo option:\u003c\/strong\u003e Supports a true stereo box configuration when two modules are used together, enabling left and right separation for custom speaker systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis board is best for electronics hobbyists, DIY speaker builders, and makers who need a small, easy-to-integrate amplifier with both Bluetooth and AUX options.
