Real Time Clock RTC
Adding a RTC to the Hive Interface board.
- Error creating thumbnail: File missing
This module almost plugs in to H2 (the I2C bus) on the Hive Interface board. A minor modification is required. As +5 VDC is not used and the ground must be shifted down a pin:
- 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.
|H2 I2C Bus|
|Pin||Signal||New H2 for RTC|
|2||+3.3||Pin 1 of H2|
|3||I2C||Pin 2 of H2|
|4||I2C||Pin 3 of H2|
|Ground for C||Ground||Pin 5 of H2|
These instructions work, but are not complete in that the RTC is not set to the ntp servers when ntp servers are available:
These instructions appear to be better but I have not tested them: https://www.raspberrypi.org/forums/viewtopic.php?t=85683
