Description:
DS3231 RTC Module is a Mini Real-Time Clock module designed for Raspberry Pi, but it also can be used for Arduino. DS3231 RTC Module IC Self-adjust 3.3V and 5V. Provide battery backup for continuous timing, and low-power consumption. Complete clock functions include seconds, minutes, hours, day, date, month and year timing, and are valid to 2100.
DS3231 RTC Module has two calendar alarms, 1Hz, and 32.768kHz output. Reset output and input buttons Debounced High-speed (400KHz) I2C serial bus. Many RTC modules are meant to operate at 5V. Unfortunately, the Raspberry Pi operates at 3.3V, and that is where this handy DS3231 RTC Module comes into play, it operates at 3.3V perfect for adding an RTC to your Raspberry Pi.
