    We will see if they are similar, but the footprint appears the same. The pricing is about the same as well. The design may have been sold off.

    The new Cardoid design we are working on might surpass this board. The two microphones are a little cheaper. So for a similar cost you get stereo or noise rejection capabilities.

    I have finished this design and it appears to work OK. I will be working on a new MEMs Mic array project shortly based on STMicro's new library. It will utilize their PDM based microphones and simulate a variety of microphone configurations. I'll update the main Flex Modules page with more details when I have it ready.
