Supply Voltage: 10-25VDC ICC, IDD: 2A or later is recommended. Output power :15W X 2 (@16V) size (length, width and height):44mm X 40.5mm X 20mm the board uses a typical circuit of TPA3110 and adopts a single power supply with anti-reverse connection. It is convenient to use a general adapter and switch power supply to power it. Most of the resistance devices use standard patch technology, which is simple and stable. A special interface is designed for the Bluetooth audio receiving module, with a 5V voltage regulator circuit inside, which can easily DIY Bluetooth speakers. The output power is 15W X 2 (@ 16V), which can be connected to 8 ohms and 4 European 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 you use a linear transformer to supply power, we recommend that you add a rectification filter board (we have a supporting sale) for a linear voltage transformation of a 9-12V (up to 15V AC) and a power of 20-30W
