This RTC module uses a low-cost, high-precision DS3231 chip. With an external high-precision crystal oscillator, you can achieve an accuracy of only one minute a year. In addition to the timing function, DS3231 also integrates some other functions. For example, the device integrates a digital temperature sensor, which can be accessed through the I2C interface alignment.
Features:
- Input voltage: 3.3-5V
- Time accuracy： 2ppm, 1 minute/year
- Suport seconds,minuutes,hours,day of week,month, year
- Support 24-hour or 12-hour format with AM/PM indicator
- Low-Power Consumption
- Two Time-of-Day Alarms
- Fast (400kHz) I2C Interface* Size: 38x22x14mm
- Weight: 8g
- RTC chip: DS3231
-
EEPROM chip: AT24C32
