DS 3231 Precision Clock Module – 507011

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, it function 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 is also consists of an EEPROM AT24C32 to supply you 32K EEPROM to store your data.
