Nobsound TPA3116+LM1036 Bluetooth 4.0 CSR8630 Audio Receiver Hifi Stereo power amplifier board 50W*2 DIY

Special Note:
The front panel switch is used to cut output, not cut off the power. Therefore, the power light is always on, not surprising. Because for this circuit,the quiescent current is very small when There is no output,
Internal circuit protection circuit has been perfect, no other access.
