Real Time Clock RTC
Adding a RTC to the Hive Interface board.
DS3231
Hardware
This module almost plugs in to J? on the Hive Interface board. A minor modification is required.
- The ground on C? must be moved.
- To be safe, the 4th pin of a 1x5 male header should be removed.
- Solder the 1x5 header in J7 BUT SHIFT IT DOWN ONE PIN.
Software
These instructions work, but are not complete in that the RTC is not set to the ntp servers when ntp servers are available:
