Review on Aideepen TDA7492P Bluetooth Amplifier Board with AC Adapter - 50W+50W Dual Channel Wireless Digital Stereo Receiver AMP Board by Derrick Siham

This turned out to be a pretty good little preamp and bluetooth board for a DIY speaker. The board gives you the ability to control the output volume in dB and installation is very simple. In addition to the board, the package includes a power supply and female and male power connectors, so you can connect the power supply in your closet without worrying about board placement. The Bluetooth connection worked great at launch and the range is acceptable for local use. I'll probably get a few more for some other projects I have in mind.
