This product is a carrier for the integrated circuit board Maxim DS1307?.
The DS1307 is a real-time clock (RTC) series of low power, we find information binary ?-coded decimal (BCD) clock and calendar as well as 56 bytes of NV SRAM relief.
Address and data are transferred serially by a bidirectional I2C bus.
The function clock / calendar provides seconds information, minutes, hours, day, date, month, and year. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock is in 24-hour or 12 hours with indicator AM / PM.
The DS1307 is equipped with a sensor that detects power failures and automatically switches to the backup power.
An open-drain output signal is intended to achieve a programmable clock at 1 Hz, 4.096Khz, 8.192Khz, 32, 768kHz; This function is very useful to synchronize your application with "to the second of reference" or one of its multiples. This output can also be attached to the logical level up or down through internal registry, allowing you to use this for debugging routines or test signal.
Three places are available for soldering the connector, you can also choose to weld a Connector? right or a90 °: it gives you the possibility of posionner at best this RTC editing in your specific applications.
Its small size, low power and ease of use make this RTC module ideal for the implementation of time for your rigs DIY systems.
For more details on the serial communication and internal registers, refer to the plug Maxim DS1307 on the tab download.
The circuit includes: the PCB with the DS1307 circuit? welded and two connectors 5 points (a right and one elbow 90 °) sold without battery.
