This RTC is designed specifically for the Raspberry where it uses the I2C communication pin on the GPIO pins of the Raspberry Pi. This module is based on the DS1307 real time clock chip uses the CR1220 coin cell battery for its operations. With this RTC the Raspberry Pi can remember the time even if the Raspberry Pi is powered off.
