Feature

●【Real Time Clock DS3231 RTC Module】: DS3231 is a cost-effective, highly accurate I2C real-time clock (RTC) with integrated temperature compensated quartz oscillator (TCXO) and quartz. Two programmable daytime alarms and a 1 Hz output are available. Address and data are transmitted serially via a bidirectional I2C bus
●Safe enough: DS3231 RTC module. A precise temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power outages and provide a reset output. In addition, it monitors that the RST pin generates a μP reset.
●【Full Clock Calendar】: RTC manages seconds, minutes, hours, day, date, month and year. For less than 31 days a month, the end date is automatically adjusted, including adjustments for the leap year. The watch works in either 24 hour format or band/AM/PM format in 12 hour format.
●【Parameters】: DS3231 AT24C32 Watch Module Real-time Clock Module Working Voltage:3.3V-5.5V Clock Chip: High Precision Clock Chip DS3231M, Memory Chips: AT24C32
●DS3231 RTC Clock Module: DS3231 Real Time AT24C32 Clock Module RTC Sensor IIC Timer The RST pin is monitored as a pushbutton input to generate a microprocessor reset.


Description

DS3231 AT24C32 Clock Module, Real Time Clock RTC IIC RTC Module for Arduino

Module parameters:
1. Size: 38 mm (L) x 22 mm (W) x 14 mm (H).
2. Weight: 7 g.
3. Packaging: anti-static packaging.
4. Clock chip: high-precision clock chip DS3231.
5. Memory chips: AT24C32 (storage capacity of 32 KB)
6. Operating voltage: 3.3 - 5.5 V.
7. Clock accuracy range: 0-40°C, accuracy 2ppm, approx. 1 minute error.
8. The chip temperature sensor has an accuracy of ± 3°.
9. Real-time clock generator for seconds, minutes, hours, day, date, month and year and provides a leap year compensation valid up to the year 2100.

Product highlights:
1. Programmable rectangular wave output.
2. RST output/push button reset debounce input
3. Two day time alarms. Simple serial port to connect to most microcontrollers.
4. IIC bus interface, the maximum transmission speed is 400KHz (working voltage 5V).
5. Can be cascaded with other IIC devices, 24C32 addresses can be short-circuited. Change A0/A1/A2, default address is 0x57
6. To ensure that the system works after a power outage, the clock moves normally

Wiring instructions (for example for Arduino r3):
SCL → A5.
SDA → A4.
VCC → 5V.
GND → GND
