Fermion: DS3231 Precise RTC (Breakout) Light/Imaging Sensors Best cost/performance ratioThis real time clock module (RTC) uses the DS3231 chip that integrates a crystal resonator and a temperature compensator, which improves the long term accuracy of the module. In the range of 40C to +85C, the accuracy of DS3231 remains at 3. 5ppm (0. 3024 seconds day). The device incorporates a battery input, and maintains high precision timing when main power to the device is interrupted. The RTC provides information of seconds, minutes, hours, week,
