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.
