DS3231 Precision RTC (Real Time Clock) Module - I2C compatible with Arduino (without battery)
€3.95
This DS3231 RTC module is an I2C-compatible real-time clock with a 32 Kbit EEPROM and a 10-bit temperature sensor (0.25 °C). It offers two daily alarms, digital temperature output, CR2032 battery power (not included), and keeps count when power fails. The temperature-compensated oscillator (TCXO) improves long-term accuracy. The I2C address is configurable to AT24C32 via jumpers A0, A1, and A2. It features a programmable square wave output and battery backup for continuous timekeeping.

The DS3231 RTC is a precise real-time clock module with 32Kbit EEPROM and an integrated 10-bit temperature sensor with 0.25°C resolution.
The DS3231 RTC module is an extremely accurate and low-cost I2C real-time clock (RTC) with a temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input and maintains accurate timekeeping when the device's main power is interrupted.
The integration of the crystal resonator enhances the long-term accuracy of the device.
FEATURES:
● Two time-of-day alarms.
● Digital temperature sensor output.
● Supports 2032 battery.
● Highly accurate, fully manages all timing functions.
● Real-time clock counts seconds, minutes, hours, date of the month, month, day of the week, and year, with leap year compensation valid until 2100.
● Configurable I2C Address device for AT24C32 using SMD jumpers on the PCB (A0, A1, A2).
● Programmable square wave output signal.
● Battery backup input for continuous timing.
● Low power operation increases battery backup runtime.
NOTE: Requires CR2032 battery (not included)
