Description
The board is a PAM8403 chip with minimal wiring and is a fairly cheap and simple audio amplifier with a supply voltage of up to 5V and an output to two channels with a power of up to 3W each..
The potentiometer on the board is convenient for the usual volume control of the device.
Perfect for a quick repair / alteration of Chinese speakers and simple low-power audio systems in which the amplifier module has failed for some reason. All contacts on the amplifier are signed and there should be no problems with its connections..
Attention! The PAM8403 chip is afraid of polarity reversal and voltage over 5V ...
