Description:
The DS3231 RTC Module is a high-precision real-time clock board with built-in temperature-compensated crystal oscillator (TCXO). It maintains accurate time and date even during power loss using a backup battery, making it ideal for clocks, data logging, and time-based automation in STEM projects.

Specifications:

Type: Real-Time Clock (RTC) Module
RTC IC: DS3231
Communication Interface: I2C
Operating Voltage: 3.3V – 5.5V
Time Format: Seconds, Minutes, Hours, Day, Date, Month, Year
Accuracy: ±2 ppm (high precision)
Onboard Crystal: Temperature compensated (TCXO)
Backup Battery: 3V Coin Cell (CR2032)
Additional Memory: 24C32 EEPROM (varies by module)
Mounting: PCB module with header pins

Features:

High accuracy timekeeping
Built-in temperature compensation
Battery backup support
I2C interface (uses fewer pins)
Stable and reliable performance

Applications:

Digital clocks
Data logging systems
Time-based automation
Alarm systems
IoT and embedded projects

Pin Identification:

VCC → Power supply
GND → Ground
SDA → I2C Data
SCL → I2C Clock

Important Note:

Insert CR2032 battery for backup operation
Default I2C address is usually 0x68
Much more accurate than DS1307
Ensure correct time initialization via code

Package Includes:

1 × DS3231 RTC Module Board
1 × CR2032 Battery (may vary by kit)
