I connected the sensor to 3.3V and GND as per developer guide first steps and I got some green flashes from the board when trying it in different orientations.
The next time, however, I got nothing at all.
The sensor board is completely dark no matter it’s orientation.
I’m using a 18650 cell and a MIC37100-3.3 as a power source which is more than enough.
What should I do?
