TDA1308 Microphone Amplifier Board
A few mailbags ago I unearthed a little red board that I initially thought might be an amplifier (the "TDA" label is usually a big hint!)
I was correct in that it was an audio module, but the little microphone in the corner was the clue that this board was a microphone plus amplifier.
After fruitlessly searching for an appropriate library I did a little "roll your own" code and found out that it works well! See for yourself in the video below.
