Giới thiệu 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)
