Real time clock
The rPi-MFC real time clock (RTC) can be used if desired. No battery is supplied. A CR2032 battery is
needed for battery backed time. It is configured as below under the Status/Control tab. The RTC is of
DS1307 type. The battery is only needed if using the Pi on a network in master mode and isolated from the
internet an
d thus NTC time server and as a Master or Remote. If using in Bridge mode a RTC isn’t needed.
GPIO inputs
There are 3 GPIO input available on CN2, CN3 and CN4 (user inputs A, B and C) which connect to Pi
GPIO23(pin 37), GPIO13(pin 33) and GPIO6(pin 31). These inputs can be used to trigger scripts.
