5.1.3. WAGO 6-pole Male Header
If a WAGO 6-pole male header is mounted on your board,your board is prepared to connect
to a phyBOARD-Wega Power Module (PEB-POW-01), or a custom power supply circuitry. The
mating connector from WAGO has the EAN 4045454120610.

5.2 Power LED D58
The red LED D58 right next to the power connector indicates the presence of the 3.3 V
supply voltage generated from the 5 V input voltage.
5.3 VBAT and RTC
On the phyBOARD-Wega the internal RTC of the AM335x is used for real-time or time-driven
applications. To backup the RTC on the module, a gold cap (C339) is placed on the phyBOARD-
Wega. This voltage source supplies the backup voltage domain VBAT of the AM335x which
supplies the RTC and some critical registers when the primary system power, VCC5V_IN, is
removed. The backup supply lasts approximately.
