The RTC2 Click board is an accessory board in mikroBus form factor, featuring the DS1307 serial real-time clock (RTC). It is a low-power, full binary-coded decimal (BCD) clock/calendar with programmable square-wave output signal. The board uses the I2C interface for communication, and can only be used with a 5V power supply. The board features a 3V/230mA lithium battery as a backup power supply, which ensures that timekeeping operation continues even when the main power supply turns off. |
