I2S digital microphone plug-in board. Power and logic levels is 3.3V MAXIMUM! All plug-in boards are manually tested.
The ICS-43434 is a bit more sensitive then the SPM1423 and noise floor a bit lower. WLED (First SR and MoonModules, later AC) will have specific profiles for both microphones to get optimal performance and except for noise floor they perform very similar in WLED SR and MM.
See Installing or Compiling for more information how to install WLED preconfigured to Shield pin layout, Microphone, ESP32 flash size and optional add ons.
Notice
Color of board and components may vary (currently SPM1423 green board, ICS-43434 black board)
Please notice that Shield or ESP32 is not included.
