- User manual: please get the link from the product description below. 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. The rtc module is specifically designed for raspberry pi. 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.
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. 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. It communicated with raspberry pi through i2c bus.

- In addition, temperature-compensated voltage reference and comparator circuits are used to monitor VCC status, the / RST monitor pin can be used as a manual input to generate a μP reset. The integrated crystal oscillator improves the long-term accuracy of the device and reduces the number of components in the production line.
Provide two configurable calendar alarms and a configurable square wave output. Rtc saves seconds, month, day, hours, and year information. A very accurate digital temperature sensor is integrated inside, which can be accessed through the I2C * interface just like time.
The working format of the clock can be 24 hours or a 12-hour format with / AM / PM indication. Months less than 31 days will automatically adjust the end of the month, including corrections for leap years.
The address and data are transferred serially through the I2C bidirectional bus. Ds3231 is a low-cost, high-precision i2c real-time clock rtc with integrated temperature-compensated crystal oscillator TCXO and crystal. Precise, detect power failures, provide reset output, and automatically switch to backup power when necessary. The module contains a battery input, date, minutes, which can maintain accurate timing when the main power is disconnected.
