Real time clock generator seconds, minutes, hours, day, date, month and year timing and provide valid until the year 2100 leap year compensation.Clock Accuracy: 0-40 ☌ range, the accuracy 2ppm, the error was about 1 minute.Clock chip: High-precision clock chip DS3231.Address and data are transferred serially through an I2C bidirectional bus.See product page link for more information about the hardware.

Provides two configurable alarm clock and a calendar can be set to a square wave output. The clock operates in either the 24 hours or band / AM / PM indication of the 12-hour format. Less than 31 days of the month, the end date will be automatically adjusted, including corrections for leap year. RTC maintains seconds, minutes, hours, day, date, month, and year information. Integrated oscillator improve long-term accuracy of the device and reduces the number of components of the production line. The device incorporates a battery input, disconnect the main power supply and maintains accurate timekeeping. Tested and works on esp8266/esp32 DescriptionĭS3231 is a low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.
