It is a low cost, extremely accurate RTC IC with communication over I2C Interface. An interesting feature of DS3231 RTC IC is that it has integrated crystal oscillator and temperature sensor and hence you don’t have to connect an external crystal. About battery type: Battery is not included, you can use CR2032 or LIR2032 battery. Clock chip: high-precision clock chip DS3231(there are 3 different chips for this clock module, DS3231N,DS3231SN and DS3231M, we send it by randomly. Voltage: 3.3-5V, Memory chips: AT24C32 (storage capacity 32K).
