Icstation PM2038 2X5W Stereo Audio Amplifier Board 5V USB Powered Adjustable Volume

Hi this is Helectronics. In this video I will review this stereo digital bluetooth amplifier. You can find the link to this circuit in the video describtion. This bluetooth amplifier circuit has three connectors, one for the power and two for the stereo output, on the other side there's a micro usb connection. As you can see it has a very small size, almost as small as my thumb. With the help of my digital caliper I measure the size of the board. It is 20.52 mm wide and 40.6 mm long. Next, I connect my phone charger and power up the board, a bright blue led indicates that it is on. Now I can search for the board with the phone, the name of the board is DW-CT14+. The continuous light indicates that the pairing is successful. I start the function generator application and with the help of the cable included with board I connect the oscilloscope to the output.
