Backup Supply
The phyBOARD-Regor is equipped with a Gold Capacitor (C339 placed next to connector X6)
which is intended to back up the external RTC (
) on the SBC. This voltage
source is also connected to the backup voltage pin VBAT (A2) of the phyCORE-AM335x and
supplies the module's RTC and some critical registers of the Power Management IC when
the primary system power, X_VIN, is removed. The backup supply lasts approximately 7
days.
