Review on 🎀 DAOKI 2PCS MAX9814 AGC Microphone Amplifier Board - Auto Gain Control Module for Arduino with Jump Wire by Julie Sutton

Revainrating 3 out of 5

Not working

On one of the two I got, the output pin seems to be biased at 1.2V with no actual signal, regardless of whether sounds are being played into the mic or the Gain/AR pins are up/down be pulled or left open. The other block seems to work fine. 1/2 isn't too bad for a small price!

Pros
  • Three stage digital input program output amplifier gain. An external resistor divider controls the AGC threshold and a capacitor programs the attack/release time.
Cons
  • None
