This module is designed specifically for the Raspberry Pi RTC module. Module uses I2C communication mode and Raspberry Pi. Onboard DS1307 clock chip and a button battery guaranteed after 1220 Raspberry Pi power still can remember the time. Set aside a serial port, TTL convenient way online debugging. Small size, big power, a battery can record for about 3 years.
