I downloaded the latest version of the installation ferduino this property passes everything works except rct .
the manufacturer of screw shiel said: @ The shield of Pins which are connected the RTC are 21 and 22 (SDA and SDL ) . Removing the battery does not stop the operation of the RTC , it is used only for backup in case of power failure .
I ' tried to connect over the screw sield the V1.1 itbd02 and rct work.
