DS3231 clock module incorporates a battery input, disconnect the main power supply and maintains accurate timekeeping. Integrated oscillator improve long-term accuracy of the device and reduces the number of components of the production line. RTC maintains seconds, minutes, hours, day, date, month, and year information. Less than 31 days of the month, the end date will be automatically adjusted, including corrections for leap year. The clock operates in either the 24 hours or band / AM / PM indication of the 12-hour format. Provides two configurable alarm clock and a calendar can be set to a square wave output. Module parameters: - Operating voltage :3.3 - 5 .5 V - Clock chip: high-precision clock chip DS3231 - Clock Accuracy :0-40 ° range, the accuracy 2ppm, the error was about 1 minute. - Calendar alarm clock with two. - Programmable square-wave output. - Real time clock generator seconds, minutes, hours, day, date, month and year timing and provide valid until the year 2100 leap year compensation. - Chip temperature sensor comes with an accuracy of ± 3 °. - Memory chips: AT24C32 (storage capacity 32K). - IIC bus interface, the maximum transmission speed of 400KHz (working voltage of 5V). - Can be cascaded with other IIC device, 24C32 addresses can be shorted A0/A1/A2 modify default address is 0x57. - With rechargeable battery LIR2032, to ensure the system after power failure, the clock move any natural normal. - Application: Servers/Telematics/Utility Power Meters/GPS Wiring instructions: SCL ? A5 SDA ? A4 VCC ? 5V GND ? GND Package included: 3 X DS3231 AT24C32 IIC module with battery

A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, provide a reset output. In addition, RST pin is monitored as generating a µP reset. Provides two configurable alarm clock and a calendar can be set to a square wave output. Address and data are transferred serially through an I2C bidirectional bus. RTC maintains seconds, minutes, hours, day, date, month, and year information. Less than 31 days of the month, the end date will be automatically adjusted, including corrections for leap year. DS3231 RTC module can work on either 3.3V or 5V. DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.
