TSA2500 is a 2x100W Stereo Bluetooth 5 multipoint audio amplifier board. It has perfect class-D architecture(Based on TDA7498) and each channel has maximum 100W power output. Both of channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC14V-39V power supply. it can be used to drive any 4Ω or 8Ω passive speakers.
The highlight point is BT 5 integrated. You can have many TSA2500 boards paired and work together. TSA2500 can remember the pairing info. You don't need pair them each time after you turn the amplifier board on. This makes it possible to build a wireless surround sound system by using the TSA2500.
If you only use one TSA2500. It can works like a common Bluetooth amplifier board. Power the amplifier board. Double click PAIR button to set the board into Pairing mode. Use your phone or PC (etc) to search for a new Bluetooth device. The module will appears as "TSA2500". You don't need a PIN, pair it and then you can play music.
