This mono audio amplifier module comprises a TDA2003A based 5W RMS power stage with volume control and an optional preamplifier stage based around a TL071 IC. Two jumper selectable audio input options are provided:
It is also possible to connect the preamp input to an electret microphone (see User Manual for details)
The module includes protection against inverse polarity, operating LED, preamp gain adjustment trimmer, power stage volume control potentiometer and connection terminals.
Supplied fully assembled and tested with instructions so you only need to make the necessary connections.Specifications
