Package List: 1 x Bluetooth Audio Amplifier Board 1 x Screwdriver Note: The power supply requirement for the product is DC12 42V 10A or above. If the power supply is 12V and the current is insufficient (< 10A), it cannot drive the high power amplifier. There is power under no load conditions, but the voltage drops sharply when loaded, and the board cannot be started. It is recommended that the minimum power supply be a switching power supply of 12V 10A or 24V 10A or above. The product is equipped with overheat short circuit protection. Please pay attention to the power connection of the product and the matching of the speaker.
