Product Description

Makerfire Raspberry Pi RTC Module Real Time Clock Module DS1307 Chip with Coin Battery

The RTC module is specifically designed for Raspberry Pi. It communicated with Raspberry Pi through I2C bus. There is a Maxim DS1307 and CR1220 button cell on the board to keep the real time for a long time after the Raspberry Pi has it’s power off. In order to offering a convenient way to debug, there are five pin has been setup which are 5v, 3.3v, Rxd,Txd on board.
There is a Maxim DS1307 and CR1220 button cell on the board to keep the real time for a long time after the Raspberry Pi has it’s power down.
Set a serial port, TTL convenient way online debugging; RTC chip: DS1307; Battery: CR1220; Work Voltage: 5V
FAQ--Question: Why does my RTC module running a wrong time when i reboot my Pi? Answer: Please do remember to disable the "fake hwclock" which interferes with the 'real' hwclock as following commands: sudo apt-get -y remove fake-hwclock sudo update-rc.d -f fake-hwclock remove
