TPA3116 Bluetooth Digital Amplifier Board

stdin:
Bluetooth uses a KCX-BT010 module.
amp:
Power amplifier TPA3116D2. Look at my terrible wiring (it shouldn't be a big problem).
audio:
Op-amp uses a 5532P op-amp, 9V power supply (using a surface-mount buck module after the previous failed integrated buck circuit).
Two 220uf solid capacitors are used as output capacitors .
IO:
A potentiometer for volume adjustment, then Bluetooth and power indicator lights (using a 5V power supply in series with a 330R resistor), infrared receiver (added on the Bluetooth module out of a momentary lapse of judgment), then previous track and next track (if a USB flash drive is plugged in), aux input.
stdout:
LC filter, around 25kHz, 3116 is available, nothing much to say.
power:
XT60 connector, those who know, know why, maximum current 30A, definitely enough for this little power amplifier.
Also, call me the layout master (not really).
After testing, the amplifier board works normally!
