Smoking Hot ZK-TB21 Bluetooth 5.0 Not a TPA3116D2 board

ZK TB21 Smoking
This is the ZK-TB21 Bluetooth 5.0 Subwoofer Amplifier Board 50W*2+100W 2.1 Channel Power Audio Stereo Bass AMP TPA3116D2 Amplifiers Board.
The amplifier claims to use the TPA3116D2 IC but this board actually use a different cheaper IC the Chipstar CS8673E.
I can't comment on how this chip performs cause the board started to smoke when it was powered up and I was not able to test the board.
Due to the poor quality assurance of this product and the chance of getting a dead board plus this board actually uses a different IC than what it says in the listing description, I could not recommend this amplifier board.
