DS1302 Real-Time Clock RTC Module (Without Battery)

The DS1302 Real-Time Clock (RTC) Module is a highly reliable timekeeping device designed to track seconds, minutes, hours, days, weeks, months, and years. Perfect for DIY electronics and data logging applications, it ensures your microcontroller project maintains accurate time even during a main power loss when paired with a backup CR2032 battery (not included).

Widely used in digital clocks, smart home automation, and IoT projects, this module is fully compatible with popular platforms like Arduino, Raspberry Pi, and ESP32. It communicates via a straightforward 3-wire synchronous serial interface, making it incredibly easy to program and integrate into your custom circuit diagram. The onboard IC also features 31 bytes of static RAM for temporary data storage.

Features:

• Accurate Timekeeping: Continuously tracks time up to the year 2100 with automatic leap year compensation.
• Low Power Consumption: Operates efficiently at very low currents, maximizing the lifespan of your backup battery.
• Simple Interface: Utilizes a standard 3-wire synchronous serial communication protocol (CE, I/O, SCLK).
• Onboard Storage: Includes 31 x 8 bytes of battery-backed static RAM.
• Wide Logic Compatibility: Supports a broad operating voltage range of 2.0V to 5.5V, working seamlessly with both 3.3V and 5V systems.

Package Includes:

1 x DS1302 Real-Time Clock Module (Battery Not Included)
