Review on π€ KNACRO MAX9814 Electret Microphone Amplifier Module with Auto Gain Control for Arduino by Jonathan Davenport
XINY MAX9814 Electret Microphone Amplifier.
Great product. I use this module in developing a low cost hearing aid for people who can only use headphones and not regular hearing aids. Five stars for the product and ten stars for the supplier from Xiny. I have developed many products but this is my first foray into audio and their support team went out of their way to help.
- Absolute legend
- Not automatic
