The 40+40 Watt Stereo Bluetooth Amplifier module measures only 55 x 38 mm but packs 2 x 40 Watt output power, Bluetooth and IR remote control capabilities.
To avoid overloading, the speaker impedance should not be lower than 4 Ohm for up to 16V supply voltage, and not lower than 8 Ohm for up to 24V supply voltage.
The maximum operating voltage range of the 40+40 Watt Stereo Bluetooth Amplifier is 8-24V, and the minimum Speaker impedance is 4 Ohm.
It has controls for volume and pause/resume on board (single knob).
After connecting power to the board, it automatically starts pairing with the last know device or can connect to a new device right away. Just look for the Bluetooth device "XY-P40W" and connect to it.
It also features several safety features like short circuit protection, overload protection, and thermal protection.
For a total output power of more than 50W is a small heatsink highly recommended.
