Diitao 6PCS Real Time Clock Module DS3231 AT24C32 IIC RTC Clock Module High Precision RTC Module 3.3V-5.5V for Arduino for Raspberry Pi(Without Battery)
ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•DS3231 16-pin Memory Chip:With an integrated temperature-compensated crystal oscillator (TCXO) and crystal.The DS3231 is an accurate I2C real-time clock (RTC)
•Feature:Integrated oscillator can improve long-term accuracy of the device.RTC maintains second, minute, hour, day, date, month, and year information. (For months less than 31 days, the end date will be adjusted automatically.)
•Function:Provides configurable calendar alarms and one configurable square wave output. Address and data are transmitted in serial via I2C bidirectional bus
•Note:The RTC module can be powered by CR2032 3V battery (The package does not not included battery)
