External Buttons port:
There have 3 buttons on the board which can control the audio volume and play/pause ect... You can connect external buttons easily by using this buttons control port.
Pins define:(Check the board backside silkscreen):
- P/P: Play pause button
- VOL+: volume increase and forward button
- VOL-: volume decrease and rewind button
- VDD_BT_IO: AudioB I2S 1.8V output
Volume control POT port:
There have an Ext POT port on the board. You can connect external POTs (5K~20K) to control the Main volume,treble,middle,Bass. You need update the DSP program first. DSP program (with external POTs). This is our POT kit
- ADC0- Main volume.
- ADC1- Bass volume.
- ADC2- Middle volume.
- ADC3- treble volume.
DSP programming port:
User can load a new DSP program by using the USBi JTAG Sigma DSP programmer
The default DSP program can auto select the Line in /Bluetooth audio and output to the amplifier chips. Bluetooth audio signal has higher priority.
2 boards work in TWS mode. You can also build a wireless subwoofer system.
- S1 - Long press 3s into pairing mode. Long press 6s clear the pairing info.
- S1+S2 - Long press 1s into TWS slave mode.
- S1+S3 - Long press 1s into TWS master mode.
- S2+S3 - Long press 1s disconnect TWS connection.

TSA8802B 2x100W 2 channels Bluetooth+DSP amplifier board with an AudioB I2S Bluetooth module that supports Apt-X. TSA8802B is a very flexible DSP/DAC/Amplifier combination board. It has perfect class-D architecture(Based on TPA3221) and 2 channels have 100W power output. All the channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC12V-30V power supply. It can be used to drive any 4Ω or 8Ω passive speakers.
It's a 2 channels amplifier board. You can pair it 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 "TSA8802B". You don't need a PIN, pair it and then you can play music.
The highlight point is ADAU1701 DSP chip on board. It has a default DSP program loaded. Customers can adjust the gain, bass, midrange and treble in the DSP program. It also have a debug port for Sigima Studio, User can program this module with our USBi programmer to get more functions which includes equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc. TSA8802B has Apt-X and TWS supported. Therefore, Users can stream audio to 2 paired amplifier boards at the same time wirelessly.
