This instruction got its flaw. DS1307 works on DC5V. But the vcc on the i2c holes got only 3.3v. So another jumper wire (DC5V) is required to make DS1307 works properly. |

As discussed in #12 , there are 4 holes on PiTray mini.
It is the i2c0 sockets, aka i2c-vc, aka GPIO 44 & 45. The rtc on CMIO4 is connected on these two pins too.
Since i2c RTC modules vary a lot, so a little bit of wire jumping may be required to build the connection. In this case, a DS1307 module.
To enable it as an hwclock, these lines need to be added to
/boot/config.txt
After reboot, you would get the device on
/dev/rtc0
. Then you may follow other instructions like disable fake clock and etc.Reference:
