Bảng Mạch Khuếch Đại Âm Thanh Kỹ Thuật Số TPA3110 30W

Features: 1.Use high-quality materials with guaranteed quality 2.Stable performance 3.Easy DIY Bluetooth speaker 4.Exquisite and compact appearance 5.Wide application range Parameters: Power supply voltage: DC8-25V Power supply current: 2A or above is recommended Output power: 30W X 2 (@ 16V) Dimension (length,width and height): 53mm X 45mm X 21mm Note: When external audio input is required,the two pads of “external audio switch“ need to be short-circuited. This board adopts the PBTL typical circuit of TPA3110,and adopts single power supply with anti-reverse connection. It is very convenient to use universal adapter and switching power supply to supply power for it. Most of the resistance-capacitance devices adopt standardized chip mounting technology,which is simple and stable. A special interface is designed for the Bluetooth audio receiving module,with a built-in 5V voltage stabilizing circuit,which can easily DIY the Bluetooth speaker. The output power is 30W X 2 (@ 16V),and the board can be connected with 8 Ω and 4 Ω speakers. Power supply description: When using a universal adapter and switching power supply,it can be directly connected to the positive and negative poles of the power supply. If a linear transformer is used for power supply,the recommended AC voltage is 9-12V (the maximum AC voltage is 15V),and the power is 30-50W linear transformer. Rectifier filter board is required Package include: Power amplifier board * 1 (with/without Bluetooth module optional)
