Review on 🔊 Onyehn Amplifier Module for Arduino with 5V and 12V Support by Ryan Gilliam

I used an amplifier to boost an electret microphone for PC input. I liked the range of the supply voltage (I used 9V, the same source as for powering the microphone). I also liked the initial configuration (I inserted a bare wire, screwed it on). I wish the input was like this. I like the red LED to indicate power. When I first tried this I thought it didn't work until I remembered the gain potentiometer; after turning everything worked. The price was much cheaper than buying the components.
