Product description: Fermion - module with real time clock RTC SD3031 - for Arduino - DFRobot DFR0998
High-precisionreal-time clock (RTC) module equipped with the SD3031 chip . It has an integrated quartz resonator and temperature compensator, which significantly improves the stability and accuracy of the module, and also ensures high precision of synchronization. The module is powered by a coin cell battery (not included), thanks to which it measures time also in the absence of power from another source. The RTC tracks seconds, minutes, hours, days of the week, months and years. It also automatically adjusts the date to the end of each month and includes leap year adjustments. The SD3031 has a built-in 70-byte SRAM for low-power data storage.
Arduino compatible product!
