The RTC2 Board features the DS1307 serial real-time clock (RTC). It is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Timekeeping operation continues even when the power supply goes off as it is then powered from the backup supply. It is easily connected to standard prototyping boards. The board comes with the appropriate schematic and software examples.
