Connected to my ESP32 board running WLED to give sound to light functionality. Really responsive, the automatic gain control works really well.

device turned up and i hooked it up and it didnt work, the SD output is short circuit to groundprobably under the chip, dont have time to get to the post office to return it so i guess that £6down the drain. most disappointed.

One worked, one faulty
Ordered two of these microphones (luckily). One of the units was faulty (did not pick up any audio at all), and on inspection the microphone chip was not squarely seated on the PCB. Other working item is as expected. Awarding 3 stars as a neutral rating given half my order was faulty and will be returned.
