15Wx2 Durable Mini Bluetooth Amplifier Board Module 4.2 Circuit Stereo Speaker Digital Module with Dual Channel Output

hi everyone I see station comm got in contact with me and they sent me these two products for review and both of them are class the digital amplifiers that are based around Texas Instruments TPAs six one one sorry three one one sixty two digital amplifier chips which we can probably one which are under the heat sinks and initially I thought that I would do two separate review on these one for this top board the red one and II and the other one the blue one but they really complement each other so I think they should be reviewed in one single video the similarities between the two that they are using the same chip and they have the same output which is 50 watts per channel and they also use quite similar working voltages so one is to have two thirty 12 to 24 volts the other one is five to 24 volts so I think they would be ideal for an old laptop power supply hopefully the main difference
