🔹 DS3231 RTC Module – Real Time Clock with Battery Backup

The DS3231 RTC (Real Time Clock) Module is a highly accurate and low-power timekeeping module with built-in temperature-compensated crystal oscillator (TCXO). It keeps track of seconds, minutes, hours, day, date, month, and year, with automatic leap-year compensation. Equipped with a CR2032 battery backup, it maintains accurate time even when the main power is disconnected.

✅ Features:

• IC: DS3231 High-Precision RTC

• Timekeeping: Seconds, Minutes, Hours, Day, Date, Month, Year

• Interface: I²C (2-wire serial)

• Operating Voltage: 3.3V – 5V

• Battery: CR2032 coin cell (included)

• Accuracy: ±2ppm (0–40°C), about ±1 minute/year

• Compact PCB design with onboard battery holder

📦 Applications:
✔️ Arduino, ESP32, ESP8266 projects
✔️ Data loggers and time-stamped systems
✔️ Real-time clocks for embedded systems
✔️ Alarms, timers, and scheduling projects
✔️ Battery-powered IoT and monitoring devices
