Muito bom esses módulos, como todos os outros que tenho comprado na BangGood. Nunca tive problema com nenhum, todos vieram muito bem embalados e funcionaram de primeira.
Simple but useful audio detector. It's not an audio amp, so the mic output is small, but can be channeled to an amplifier. The threshold detect is set with the pot, and has a nice LED to show detection. It's a useful module if your sound source is loud.
