“Arrived well packaged. Using it with esp32 and micropython, works very well, I tested it against the Ultrasonic Distance Sensor (HC-SR04). Only very basic detection use at the moment while I play around with it. Straight forward to wire up and use though :-)”
“Miniature microphone, very easy to use (in my case with Raspberry Pi Pico), worked exactly as expected and good instructions are available from SparkFun.”
