High-precision IIC DS3231 Electronic Clock AT24C32 Module
The DS3231 is a low-cost, highly accurate Real Time Clock Module which can maintain hours, minutes and seconds, as well as, day, month and year information.
It also has automatic compensation for leap-years and for months with fewer than 31 days.
The DS3231 is a low-cost I2C RTC, with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.
Compared to the DS1302 solution, the DS3231 has many advantages, its functions with a VCC ranging from 2.3V to 5.5V and has a battery backup.
Unlike the DS1307, the DS3231 also has an integrated crystal, temperature sensor, 2 programmable time-of-day alarms, and a 32.768 kHz output pin to ensure higher accuracy. It also consists of an EEPROM AT24C32 to supply you 32K EEPROM to store your data.
