All about the product
The OPA344 is a microphone amplifier module from SparkFun. It features a microphone connected to an amplifier, allowing users to use it in their projects immediately without the hassle of matching amplifiers and microphones. The microphone works by converting the vibrations of the plate caused by sound waves into an electrical signal, which is amplified by the amplifier. The module sends that signal to the analog input of a microcontroller.
