Here's the single PCB version of the LoRa motion detector:
It works as expected. The entire board is roughly the size footprint as the 3x AA batteries that are a part of it. Thanks to @NCA78, it's using an XC6206 LDO.
I just received a 3D printer kit today. I suppose the next step will be to print a 3D case for it. Ideally I'd like to make it waterproof/moistureproof so that it can also work outdoors.
It is actually called a radiation shield. Too bad you don't have a 3D printer. I did a design for one that I have posted on thingiverse.
0.45mm pitch, it will be a pain to hand solder and the big ground pad at the bottom is out of reach, get a stencil.

It's very simple
No stencil?
Another one that seems promising is the LP2950 series. Just wondering if anyone has had any experience with these?
@toyman Looks like a DIY watch, using one of the very small nRF52 modules and a small OLED screen (or maybe ePaper?) would be fairly easy to design and put together.

Making it aesthetically pleasing is probably much harder! Still, maybe a DIY bridge would tide you over until a more proper watch is available for conversion. Interestingly, it looks like they made their case from stacked pieces of laser cut acrylic.
Unfortunately, theirs is impractically large:
@alowhum Doesn't answer your question, but I use just regular FTDI to listen to the serial output from the nRF5. So, there's always that for you to fall back on.
@berkseo Thanks! I just ordered it to test how easy/hard it is to solder. If I can manage that, then I may switch over to it.

@alowhum I'm not sure the function call that reveals that amount of free memory available, but I'm sure there must be one. Logging that as a diagnostic would reveal whether you have a memory leak in your code.
