For Raspberry Pi SensorGnomes, the software runs entirely off the MicroSD card; if the proper software isn’t present on the MicroSD card, the RPi SG won’t function properly. This can cause issues for teams who are unaware of this – and who expect to be able to simply swap out one card without ensuring that the new card has the proper software on it. But it also makes updating the software with a clean installation very simple; all you need to do is copy the software files onto a blank SD card.
