Description

 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.

			==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:<br>
			<pre>
			sudo apt-get -y remove fake-hwclock
			sudo update-rc.d -f fake-hwclock remove
