SIGNAL AMPLIFIER OP-AMP MODULE (LM358)

The LM358 operational amplifier module is handy for providing basic waveform amplification in a project such as boosting a signal from a microphone. The gain has a range of 1x to 100x and is adjustable using the multi-turn potentiometer on the module.  Turning the pot CW lowers the amplification while turning it CCW increases it. An power LED is included on the module.
