Anyone know of a breakout board for a SPM0404UD5 or any other similar ultrasonic MEMS sensor? I want to build a ultrasonic detector so I'm looking for something that can detect the presents of ultrasonic sound (if you could call it that ).
Thanks

Didn't even think of that, but it makes sense.

These sensors will likely only every be on breadboards. I wonder about this as on the backside of the board is where they put the pin descriptions which made me wonder if I had been putting the headers on the wrong side, plus I was wondering if having the sensor side down might shield the sensor from drafts etc.

Got a number of BME280 sensors and I'm wondering better to solder the header on with the sensor up or down.
