FEZ Raptor with G400

I see that the Raptor has a RTC circuit. Is there a connector for an external battery to keep the clock running?

@ dspacek - pin 5 on socket 5, the “Z” socket.

Is there a Gadgeteer module with a battery holder for a CR2032 disk battery?

@ dspacek - GHI does not sell a battery module that supports the CR2032. Digikey sells those types of battery holders.

Maybe that will be the first custom board I make - a small board that just has a battery holder and plugs into a Z Socket. We sure could use one.

or… SD2403 Real -Time clock Module(Gadgeteer Arduino Compatible)

I found something - almost a Gadgeteer module:

20mm Coin Cell Breakout Board (CR2032)
PRODUCT ID: 1870
$2.50

The Z socket is relative. You would need to allow a jumper for 7 pins to connect in case the vbat is on another pin from the Raptor. It is on pin 8 for Cerberus.
