This product uses high-quality PCB circuit boards, which are flat and not prone to bending, and have a long service life.<br/>2. The Bluetooth power amplifier board can be used as a single chip, with a single channel dual speaker. After pairing with two TWS, it can form four channels and connect to four speakers.<br/>3. Stable performance, strong signal reception, and a straight-line distance of over 15 meters.<br/>4. Supports Bluetooth amplifiers, can be used by connecting the power and speaker, wireless transmission, and high fidelity sound quality.<br/>5. Widely applicable in various fields, including Bluetooth speakers, toys, massage chairs, household appliances, electric vehicles, lighting, photovoltaic products, fitness equipment, and more.</div><br/><p><strong><span style="font-size:20px">Parameter:</span></strong><br/>Bluetooth version: 5.0<br/>Bluetooth name: PASPDX-FW65ABT-TWS<br/>Transmission rate Mbps: 48<br/>Input voltage: DC8-24V (can be powered by lithium batteries or DC power supply, pay attention to the direction of the positive and negative poles of the power supply, reverse connection will burn out the circuit board.)<br/>Output power: Single board power: 50W+50W; TWS two boards connected power: 50W+50W+50W+50W+50W<br/>Effective communication distance: 15m<br/>Size: 72mm * 35mm</p><p><strong><span style="font-size:20px">Kind reminder:</span></strong><br/>*The circuit board has been tested before shipment, and its use is a technical activity. Connecting it incorrectly can burn the board. You need to have suitable power and speaker accessories, electronic foundation, and correct wiring in order to work properly. Please meet the above conditions before placing an order.<br/>*Bluetooth name: PASPDX-FW65ABT-TWS<br/>*TWS pairing method: When two Bluetooth boards are powered on, they will automatically pair up to form a four channel output<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/>*This link only has a board and there is no delivery line by default; We do not provide speakers and batteries<br/>*The standard configuration of the speaker is 8 Ω 30W-50W. When using a 4 Ω speaker, it is recommended to use it below 12V, as excessive output can cause protection<br/>*Avoid installing in metal sealed spaces as it may affect Bluetooth signal reception and cause intermittent or silent sound<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</p><p><strong><span style="font-size:20px">Package include: </span></strong><br/>1X module<br/></p></div></div><br/>
