Supports TWS BT solution, with single board supporting mono and dual board supporting TWS pair stereo operation. <br/>2. Adopting the TPA3110-PBTL circuit, the maximum output power reaches 30W. <br/>3. Built in voltage regulator circuit, supports universal adapter power supply, easy to use. <br/>4. Compact size, suitable for various DIY BT speaker projects. <br/>5. No need for an external volume adjuster, directly control the audio size through your phone.</div><br/><p>Product Introduction: <br/>This board adopts the TWS BT solution, and a single circuit board can be used as a single channel BT amplifier board. When two circuit boards work together, they automatically pair to form a TWS stereo dual channel BT amplifier. <br/>The power amplifier adopts a typical circuit of TPA3110-PBTL, with a maximum output power of 30W (@ 4 ohms, 16V or above). It is powered by a single power supply with anti reverse connection, which is convenient to use universal adapters and switch power supplies, or ordinary linear transformers with rectifier filter plates for power supply. Most of the resistance and capacitance devices use standardized surface mount technology, which is simple and stable. Adopting an integrated design with built-in BT audio reception and a built-in 5V voltage regulator circuit, it is easy to DIY BT speakers. The output power is 30W (@ 4 ohms, 16V), and the board can be connected to speakers of 8 ohms and 4 ohms. A single circuit board is a mono, and two circuit boards can be paired to form a stereo dual channel BT amplifier.</p><p>Parameter: <br/>Power supply interface: DC 5.5*2.1mm <br/>Supply voltage: DC 9-25V ， The optimal power supply voltage is DC15-22V <br/>Power supply current: 3A or above is recommended <br/>Output power: 30W (@ 4 ohms, 16V or above), single-chip circuit board <br/>Size: Approximately 55MM in length, 36MM in width, and 13MM in height <br/>Note: This board does not have a volume adjustment potentiometer, and adjusting the audio requires operation through a mobile phone.</p><p>Package Include: <br/>1X power amplifier board<br/></p></div></div><br/>
