🚀 What Makes It Great

• Precision Timekeeping: Thanks to the TCXO, this module holds time accurately within a few minutes per year — far better than standard RTCs under temperature variation.

• Battery Backup: With the included CR2032 battery socket, it keeps the clock running and preserves time through power cycles or outages.

• Easy Integration: Uses the I²C interface (SDA & SCL), making it compatible with platforms like Arduino, Raspberry Pi, ESP32, and other microcontrollers.

• Low Profile & Handy: The compact board fits neatly in many project enclosures — perfect for clocks, data loggers, automation systems, and any application needing reliable “real-world” time.
