The specifications indicate that a 32kHz crystal is required for the real-time clock. Am I correct in believing that is out of date, and all that is necessary is supplying 1.2 volts to VBAT?
@ rileysuit - That depends on which Hydra that you are referring. The Hydra+ and version 1.3 of Hydra only require the 1.2V for the VBAT. All other versions of the Hydra will still require the 32kHz crystal as well.
The specs for the Hydra+ still say that a crystal is needed. Just saying.
@ rileysuit - Hydra+ specs have been updated.
