DS3231 High Precision RTC Clock Module For Raspberry Pi (ER-RPA32311R)
DS3231 High Precision RTC Clock Module for Raspberry Pi (ER-RPA32311R)
This module based on the DS3231, it is the foreign high precision clock module for Raspberry Pi and Arduino. Device package and function compatible with the DS3231.Complete clock calendar functions including seconds, minutes, hours, day, date, month and year timing. The module can adapt itself 3.3 V and 5 V system without level conversion, it is super convenient!
Features
- to 40℃ to + 85℃ temperature range, timing accuracy in a plus or minus 5 PPM (+/- 0.432 SEC/day)
- To provide continuous timing battery backup
- Low power consumption
- The device compatible with DS3231 encapsulation and function
- Complete the clock calendar function including the second, minute, time, week, date, month, and year, and provide the valid until 2100 leap year
- Two calendar clock
- 1 Hz and 32.768 kHz output
- Reset the output and input button to tremble
- High speed (400 KHZ) the I2C serial bus
- + 2.3 V to + 5.5 V power supply voltage
- The accuracy of plus or minus 3℃ digital temperature sensor
- – 40 ℃ to + 85℃ temperature range
DS3231 sú lacné, extrémne presné I2C hodiny reálneho času (RTC) s integrovaným teplotne kompenzovaným kryštálovým oscilátorom (TCXO) a kryštálom. Zariadenie obsahuje batériový vstup a udržiava presné meranie času, keď dôjde k prerušeniu hlavného napájania zariadenia.
