Reliable Sensor

Bought multiple units for a class project. All functioned perfectly out of the box.

Great for Arduino

Used this for a voice logger project. The AGC keeps levels consistent even when I move away from the mic. Very satisfied.

Okay for beginners

It works but requires some knowledge of audio biasing to get the best signal quality.

Good module

Works well. Only giving 4 stars because the pin headers were not included in my batch, had to solder my own.

Excellent AGC Performance

The automatic gain control is smooth. No pumping effects noticed during testing.

5 FAQ

Q: Does it have a mute function?

A: No, this specific module does not feature a hardware mute pin.

Q: Is the microphone included?

A: No, this module is the amplifier only. You need to purchase an electret microphone separately.

Q: What is the power consumption?

A: Typical supply current is approximately 1.5mA during normal operation.

Q: How do I adjust the release time?

A: Release time is typically set by an external capacitor connected to the REL pin according to the datasheet.

Q: Can this work with 5V Arduino?

A: Yes, the supply voltage range supports 5V logic systems perfectly.
