Stable performance, strong signal reception, and a straight-line distance of 15 meters.<br/><br/>2. The input voltage supports DC5-24V, and can also be powered by lithium batteries or DC power sources. The higher the current, the more sufficient the output power.<br/><br/>3. The output power is high, with a peak power of 100W for a single board and a peak power of 100W+100W for TWS boards connected in pairs.<br/><br/>4. Easy to use, Bluetooth amplifier can be used by connecting to the power and speaker, wireless transmission, and high fidelity sound quality.<br/><br/>5. Using original chips, output in PBTL mode, configured as a 100W Class D mono audio amplifier in PBTL mode, capable of driving a 2 Ω 100W speaker in sufficient current scenarios.<br/><br/><strong><span style="font-size:20px">Product parameters:</span></strong><br/><br/>Chip: TPA3116<br/><br/>Input voltage: DC 5-24V<br/><br/>Output power: Single board peak power 100W, TWS two boards connected peak power 100W+100W<br/><br/>Power supply: Lithium ion battery or DC power supply (the higher the current, the more sufficient the output power.)<br/><br/>Effective communication distance: straight-line distance of 15 meters<br/><br/>Bluetooth name: BT-TWS<br/><br/>Size: 40x35x15mm<br/><br/>Application areas: Bluetooth speakers, toys, massage chairs, household appliances, electric vehicles, lighting, photovoltaic products, fitness equipment, and so on.<br/><br/>Attention: Only when the power supply voltage/current is sufficient can there be sufficient power output. A higher power supply voltage will result in a higher relative output power, and speakers with different impedances will have different output power. When the voltage and current are sufficient, the greater the Ω of the speaker. The smaller the relative output power, the smaller it will be.<br/><br/><strong><span style="font-size:20px">Kind reminder:</span></strong><br/><br/>*The circuit board has been tested before shipment. The use of the circuit board is a technical activity, and connecting it incorrectly can burn the board. You need to have suitable power and speaker accessories, electronic foundation, and correct wiring to work properly. Please meet the above conditions before placing an order.<br/><br/>*TWS pairing method: When the Bluetooth board is powered on, the two boards will automatically pair. After about 15 seconds of successful pairing, open the Bluetooth connection on the phone.<br/><br/>*Before purchasing, please confirm if this circuit board meets your needs. You will need to provide an additional speaker and power supply to complete the matching.<br/><br/>*This link only has a board and there is no delivery line by default; We do not provide speakers and batteries.<br/><br/>*The standard configuration of the speaker is 4 Ω 50W-100W<br/><br/>*Avoid installing in metal sealed spaces as it may affect Bluetooth signal reception and cause intermittent or silent sound.<br/><br/>*Pay attention to the positive and negative poles when wiring the power supply! Please use within the calibrated voltage range. Misconnections and high voltage can burn the board, while low voltage will not work.<br/><br/><strong><span style="font-size:20px">Product List:</span></strong><br/><br/>1X amplifier board<br/><br/><br/></div><div><br/></div></div></div><p><br/></p>
