Mini version 50Wx2 Bluetooth digital power amplifier board (knob to adjust volume with switch)
The potentiometer adjusts the volume, with a switch, which is convenient to control the volume, which is very suitable for DIY speakers.
If it is a metal box, you need to lead out the Bluetooth antenna.
It adopts copper DC connector, which can withstand large current and does not generate heat.
Capacitor 470uf35V solid capacitor, to ensure power storage and heat dissipation capacity, stable and continuous power supply is the premise of good sound quality.
The DC head wire is sent, which is compatible with the input power interface of this product, even if you do not have a DC head adapter or battery, you can also connect easily.
5.0 Bluetooth version, higher transmission efficiency and longer transmission distance.
The power amplifier module does not contain a power supply, and an external power supply is required, and it can also be connected to a notebook power supply. If you need power, please click the link: the switch is a standby switch. After turning off the switch, the machine is in a low-power standby state. To completely turn off the power or not use it for a long time, you can unplug the DC plug on the machine.
