Product Brief Introduction
This board adopts the typical circuit of TPA3110 and uses a single power supply with anti reverse connection. It is very convenient to use a universal adapter and switch power supply, or a common linear transformer with a rectifier filter board for power supply. Most of the resistance and capacitance devices use standardized surface mount technology, which is simple and stable. Adopting an integrated design with built-in Bluetooth audio reception and a built-in 5V voltage regulator circuit, it is easy to DIY Bluetooth speakers. The output power is 15W X2 (@ 16V), and this board can be connected to 8-ohm and 4-ohm speakers.
