DS1302 REAL-TIME CLOCK (RTC) MODULE WITHOUT BATTERY
 

The DS1302 real time clock module is designed for arduino compatibility and does not include a battery.

It integrates a trickle-charge clock chip that incorporates a real-time clock/calendar and 31 bytes of static ram.

The module communicates with a microcontroller through a simple serial interface, requiring minimal pins.

With the help of a precise oscillator and a small battery, the RTC module maintains accurate timekeeping (not included).

In numerous applications, it provides an exact date and time.
 

It operates within a wide voltage range of 2.0V to 5.5V, with an operating current of less than 300nA at 2.0V.
The clock module offers options for single-byte or multi-byte data transfer, and it comes in an 8-pin DIP or optional 8-pin SOIC surface mount package.
It is compatible with 3.3V or 5V SCM, and it features a 3V 260mAh backup battery (non-rechargeable) for maintaining data and clock information in low-power situations.
The module includes a 32.768KHz crystal oscillator and has a working temperature range of 0°C to 70°C.
It has four positioning holes with a diameter of 3.1mm for easy installation compatibility.

Any time-sensitive applications like attendance systems, digital cameras, automatic sprinkler systems, or a time and calendar display benefit greatly from the RTC module.
