High performance Bluetooth chip, equipped with the new version of Bluetooth 5.0 for more stable transmission and stronger signals, with no pressure on Bluetooth transmission/reception. <br/>2. Genuine materials are more durable, reducing the size of PCB circuit boards and making the layout of components and wires more reasonable, thereby increasing the product&#x27;s service life. <br/>3. PCB board with a 40 * 40mm micro design, small size, high power, and can support up to 50W. <br/>4. Supports 5.0 high-definition Bluetooth connection up to 20 meters in open space, with up to 50W output per channel under 24V input voltage. <br/>5. Easy to use, adjustable volume board, can be directly embedded in the chassis or speaker.</p><p>Product Introduction: <br/>The new micro amplifier board is launched, which is a 40 * 40mm micro design. Despite its small size, the power is not small. The onboard TPA3118D2 amplifier chip supports 5.0 high-definition Bluetooth connection and can reach up to 20 meters in open space. It can output up to 50W per channel under 24V input voltage. The volume can be adjusted onboard and can be directly embedded in the chassis or speaker. <br/>The red terminal is the power supply terminal, supporting up to DC24V input, and the white terminal is the audio output connected to the speaker, which can drive the continuous operation of the 4 Ω speaker.</p><p>Parameter: <br/>Product Name: Bluetooth Digital Amplifier Board <br/>Supply voltage: DC12-24V <br/>Output power: 50W * 2 <br/>Number of channels: 2 <br/>Bluetooth version: 5.0 HD <br/>Lead length: 24 # L=150mm <br/>Volume adjustment: 50K dual potentiometer <br/>PCB board size: 40 * 40mm <br/>Installation hole spacing: 36 * 36mm <br/>Bluetooth connection instructions: After power on, the Bluetooth indicator red light will light up, followed by a prompt sound waiting for Bluetooth connection, and the Bluetooth indicator blue light will quickly flash; After Bluetooth connection, the prompt sound will tell you that the Bluetooth connection is successful, and the Bluetooth indicator light will stop flashing. When playing a song, the indicator light will flash at a low frequency.</p><p>Package Include: <br/>1. Power amplifier board * 1 <br/>2. Wires * 3 <br/>3. Aluminum alloy knob * 1 <br/>4.
