“Brilliant little add-on to get audio. I use mine as a prototyping baby monitor in a Pi Zero to experiment with our current Pi 3 powered baby monitor which works well. Had a few teething problems but was due to not having the mic level up all the way and the fact that in the version I got, there is no LED. Support was fantastic and sent a replacement one because I thought the first was faulty, but there were no issues with them both.”
“Same as first review for me - sound inaudible at highest record and playback settingv - so as much use a a chocolate teapot.
On the other hand it was not too difficult to plug it into the USB socket.”
