Internal Battery
On the board a battery type CR2032 in a battery socket is used to keep RTC time and date running if the board is
not powered. As default on delivery the battery is isolated to the upper socket spring contact with an isolation
tape. It is recommended to remove this tape if the board is used in the application so that the battery can supply
the RTC unit and to reinstall the isolation tape if the board is stored for a longer period. This will prevent the
battery from discharge.
