TSA1740 is a 2x20W Bluetooth 5.0 audio amplifier board. It has a digital amplifier chip YDA174 on the board. It is a 20W×2ch high performance digital audio power amplifier IC with two DSPs. This board can be powered by any DC10V-18V power supply. It can be used to drive any 4Ω or 8Ω passive speakers. It's perfect for your Hi-Fi application. You may wish to pair with a mobile phone or a computer (etc). Power the amplifier board. Use your phone or PC (etc) to search for a new Bluetooth device. The module will appear as "TSA1740". You don't need a PIN, pair it and then you can play music.

The highlight point is you can connect multi TSA1740 to let them works together. It's a Bluetooth network. When you set the board to "party modue", users can stream audio to many amplifier boards at the same time wirelessly.
