Both the IMX678 and IMX412 have a green status LED on the back that flashes once it is "running".  

This is what we are seeing:

IMX412:  short flash, then green LED remains on while running / RTSP streaming
IMX678:  short flash, then 4 second green LED, 4 seconds LED off, repeat

We do see RTSP streams with both cameras but often they cut out and trying to start with the LED status to debug, also knowing what we should see on the LED is helpful for mfg techs to confirm functionality.

Hi @sspiller 
This LED, D6, is an indicator that all power supplies for the board are ON (and GOOD) and the image sensor is OUT OF Reset.

When you see it toggling OFF, it implies the VOXL/VOXL 2 is holding the image sensor in reset.
