Description

The DS3231 module is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accurate timekeeping when main power to the device is interrupted.

Parameters

• High-precision clock chip DS3231

• Working voltage: 3.3--5.5V

• The real-time clock generates seconds, minutes, hours, days, dates, months and years

• IIC bus interface, the maximum transmission speed is 400KHz (when the working voltage is 5V)

• With battery CR2032, to ensure that the clock still moves normally after the system is powered off

• Memory chip: AT24C32 (storage capacity 32K)

• Dimension: 38mm(L)*22mm(W)*14mm(H)
