DFRobot (DFR0821) Precise RTC Module, Fermion, DS3232, Arduino Board

Product Information Accessory Type: DS3232 Precise RTC Module For Use With: Arduino Board Product Range: - Product Overview Fermion DS3232 precise RTC (breakout). This real-time clock module (RTC) uses the DS3232 chip that integrates a crystal resonator and a temperature compensator, which improves the long-term accuracy of the module. In the range of -40°C to +85°C the accuracy of DS3231 remains at ±3.5ppm (±0.3024 seconds/day). The DS3232 integrates 236byte SRAM storage that can store data with extremely low power consumption and it also can be used in scenarios such as low power consumption collection of the Internet of Things. The device incorporates a battery input and maintains high precision timing when the main power to the device is interrupted. The RTC provides information of seconds, minutes, hours, week, day, month and year and it can automatically adjust the date at the end of the month, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator.
