DS3231 RTC modul nagy pontosságú AT24C02 EEPROM-mal és I2C interfész valós idejű óramodullal az Arduino számára
DS3231 RTC Module with AT24C02 EEPROM High Accuracy and I2C Interface Real Time Clock module for Arduino
Description
Based on DS3231, this is high-precision real-time clock module. DS3231 can not only do the timing, set two alarms and it can also measure temperature.
Onboard AT24C02 EEPROM, you can record more alarms and events information. Onboard CR1220 battery holder, it is convenient to keep timing when main power to the device is interrupted.
