Jarrett@Kris Winer used this sensor on the #STM32L4 Sensor Tile, and it looks pretty interesting for an application I have in mind.
I was originally, a long time ago, going to use a different electret microphone (the SPM0408LE5H-TB-6), but that was analog output, no amplification, nothing special.
This thing is a complete package, with I2S output. Seems awesome.

Shown with a Digikey ruler. I'm liking this for scale, I might do it all the time.
Problems:
That hole for the microphone wasn't wide enough to actually be a hole. It was filled up with dried soldermask. A small drill bit cleared that right up. Note to self, make the hole bigger in my footprint. It's currently not a via, and it's probably best to keep it that way so as to not encourage solder to flow into the hole.

Other problems: I don't see a bypass capacitor on VCC nor a 100 K resistor on SD to GND to allow the voltage to drain when the data line is deselected. Take a look at the datasheet to understand why these two might be important. Missing these doesn't mean the mic won't work, it just means it won't work well....
Are you sure? yes | no
Excellent corrections, thanks!
It's clear that I haven't more than the most cursory glance at the datasheet so far :P
