💻 Product Overview
This is a serial real-time clock module built around the DS1307 chip, a low-power clock and calendar that also carries 56 bytes of non-volatile SRAM. It keeps track of seconds, minutes, hours, day, date, month and year, and continues timekeeping from a backup supply when main power fails. It is aimed at electronics hobbyists and developers who need reliable time and date data in a microcontroller project.
✨ Key Features
- Clock and calendar: Tracks seconds, minutes, hours, day, date, month and year.
- Automatic date correction: Adjusts the end of the month for months shorter than 31 days, including leap year.
- Two time formats: Runs in 24-hour or 12-hour mode with an AM/PM indicator.
- Serial interface: Address and data move over an I2C bidirectional bus.
- Backup switching: A built-in power-sense circuit detects power failures and switches to the backup supply.
- Non-volatile memory: Provides 56 bytes of NV SRAM alongside the clock.
