Module Memory 2Pcs Real Time DS3231 RTC For Arduino Practical Universal
Features:
* DS3231 is a extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.
* The device incorporates a battery input, disconnect the main power supply and maintains accurate timekeeping.
* The DS3231 is available in commercial and industrial temperature ranges, using a 16-pin 300mil SO package.
* RTC maintains seconds, minutes, hours, day, date, month, and year information.
* 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
* 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.
* Address and data are transferred serially through an I2C bidirectional bus.
* A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, provide a reset output, and if necessary, automatically switch to the backup power supply.
* The device integrates a very precise digital temperature sensor, through the I2C interface to access it (as the same time).
* This temperature sensor accuracy is ± 3degree Celsius
* On-chip power supply control circuit can automatically detect and manage the main and standby power (i.e., low-voltage battery) to switch between the power supply.
* This module don't have battery,please know it !!!
Specifications:
* Operating voltage :3.3 - 5 .5 V
* Clock chip: high-precision clock chip DS3231
* Clock Accuracy: 0-40degree Celsius range, the accuracy 2ppm, the error was about 1 minute
* Memory chips: AT24C32 (storage capacity 32K)
* Chip temperature sensor accuracy:±3degree Celsius
* Dimensions: 38* 22*14mm (approx)
Package contents:
