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
It is most likely OP amp output you are seeing,
connect 5v, resistors as needed and multimeter to resistor output, check if works satisfactory, simple....
Well there is no more sense in any of us wasting any of our valuable resources (time, thought) if it will not affect the design anyway, since you have already ordered the parts.
Ignorance is fine, inconsideration for other people's time and effort is not (at least with me).
I realize you are in a hurry to build something, we all are, but some times when you hurry you cost yourself time. Or other opportunities like feedback and chance to modify the design. All of which are irrelevant now (at least insofar as this particular project)...
We still expect pictures of the completed project.
Good to hear you got it sorted!
@mountainman said in Sensebendermicro.ino verify errors:
I also got platform.io setup so I'm going to transition to using it going forward in order to help pin the dependencies.
Neat! I'm really curious to hear how you get on with it.
But then I thought, maybe better make a separate thread for that, so I did so here.
@TRS-80 I have no idea what exactly he posted then, but description matches I've read a review of this modules with some tests, and it was looking promising. But don't expect 3A from those exact small modules, to small inductor for such current.
@projectMarvin
indeed nrf52 + mysensors fota is not officially supported.
When I tried fota, I used nordic/Adafruit (secure) bootloader and derived it (because we used adafruit core + mysensors).
That was a while ago.. but actually I prefer and need subghz.
Unfortunately I'm working on others fun projects so I don't have time to work on nrf5 for the moment.
Sure using mobile app for fota is not convenient. better code a server-side app, micro service, for this task.
@monte said in Just found a pair of "old" NRF51822-04 ... any good?:
Though the power bug @Nca78 mentioned is easily bypassed with proper software settings. Just don't rely on built in sleep function, because in case of nfr51822 it doesn't disable all hardware and drains power.
Sorry @monte, I'm totally n00b . Any link about this?

Oh, I know! But I lack time to tinker that much. I've just started on learning on Black Magic Probe and STLink differences and use cases... Maybe I just started the hard way, with a DK it would be, at least, less "pioneeristic".
