Overview
The board adopts TWS bluetooth program, the single circuit board can be used as a mono bluetooth amplifier board, when the two boards work together automatically couples to form a TWS stereo dual-channel bluetooth amplifier.
Amplifier part of the TPA3110-PBTL typical circuit, the maximum output power in 30W (@ 4 ohms, 16V or more), using a single power supply with anti-reverse connection, it is very convenient to use a common adapter and switching power supply, or an ordinary linear transformer plus the rectifier filter plate for its power supply, capacitance resistance devices most of the standardized SMD process, simple and stable. Built-in Bluetooth audio receiver integrated design, built-in 5V voltage regulator circuit, you can easily DIY Bluetooth speaker. Output power of 30W (@ 4 ohm, 16V), the board can be connected to 8 ohm, 4 ohm speakers, a single circuit board for mono, two circuit boards can be linked to form a stereo dual-channel Bluetooth amplifier.
