RTC DS3231 I2C real time clock module - STEMMA QT/Qwiic - Adafruit 5188
A real-time clock (RTC) module from Adafruit. It features the DS3231 chip, which integrates a quartz resonator and temperature compensator to significantly improve the module's accuracy. The accuracy of the DS3231 is ±3.5 ppm (±0.3024 seconds/day). The DS3231 I2C Real-Time RTC clock module also features a battery slot, allowing the module to maintain high timing accuracy even when the main power supply to the device is interrupted. The module also features STEMMA QT / Qwiic connectors for convenient connection.
