This 2 x 30 Watt Class-D Audio HiFi Amplifier board features the TPA3110 amplifier chip with high efficiency, low distortion and a high signal-noise ratio of about 100dB.
The recommended speaker impedance is 4-8 Ohms.
A DC power supply of 8-26V is required and it should be clear that only a high voltage will result in the maximum output power and that the power supply also needs to be able to deliver the required current of up to 3.5A. Please refer to the diagrams in the TPA3110 datasheet.
Inputs, Outputs and Power Supply Connections are clearly marked on the module and don’t require any further instructions. Again, if you have questions about certain details, have a look at the datasheet.
Module size is 53 x 45 mm
