Raspberry Pi RTC Module DS1307 Real Time Clock Module with BAT and Coin Battery for Raspberry Pi #adMakerfire #ad
- The rtc module is specifically designed for raspberry pi. Set a serial port, ttl convenient way online debugging; RTC chip: DS1307; Battery: CR1220; Work Voltage: 5V. User manual: please get the link from the roduct guides and documents below.
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. In order to offering a convenient way to debug, 3.
3v, rxd, there are five pin has been setup which are 5v, 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: sudo apt-get -y remove fake-hwclock sudo update-rc.
D -f fake-hwclock remove. 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.
