Panoramica del prodotto
DFR0998 is a Fermion: SD3031 Precision RTC Module for Arduino. This real-time clock (RTC) module uses the SD3031 chip, which has an integrated crystal oscillator and temperature compensator. This provides high-precision timing and stability. At a temperature of 25°C, the accuracy is maintained at ±3.8ppm (±0.32832 seconds/day). The SD3031 can be powered by button-cell batteries. This allows for accurate timing even when the main power source is interrupted. The RTC keeps track of seconds, minutes, hours, days of the week, dates of the month, and months and years. It also automatically adjusts the date at the end of each month and includes leap year corrections. The SD3031 has a built-in 70-byte SRAM for low-power data storage.

Contenuti
Fermion: SD3031 RTC module (Breakout), 2.54-7P black single-row pin connector.
Note
Due to recent air cargo regulations, special items such as batteries, magnets, and liquids are strictly audited for air transport. As a result, the RTC module does not come with batteries. You will need to purchase them locally. The button cell model that is compatible with this module is CR1220.
