Mini RTC I2C DS1307 + 24C32 Module

This Mini RTC I2C DS1307 + 24C32 Module combines a DS1307 real-time clock with a 24C32 EEPROM to provide reliable timekeeping and non-volatile data storage in a compact form factor. Engineered for I2C communication, the module integrates easily with a wide range of microcontrollers and development boards used in embedded projects.

• DS1307 RTC chip for stable time tracking with low power consumption.
• 24C32 EEPROM offering 32KB of non-volatile memory for persistent data retention.
• I2C interface for simple two-wire connectivity and broad compatibility.
• Backup battery support to maintain clock operation during power interruptions.
• Compact PCB design suitable for space-constrained applications.

By combining clock and memory functions on a single module, this unit reduces wiring complexity and saves board space compared to separate RTC and EEPROM components. The DS1307 uses a quartz crystal oscillator to deliver consistent timing performance, while the integrated 24C32 EEPROM enables storage of configuration data, logs, calibration values, or small datasets that must persist across power cycles. A dedicated backup battery input preserves the real-time clock when main power is lost, making the module appropriate for data-logging devices, time-stamped event recording, scheduling systems, and other embedded applications requiring both reliable timebase and persistent memory.

Simple I2C addressing and straightforward integration make this module suitable for rapid prototyping and production designs where dependable timing and local non-volatile storage are required.
