Description:
The DS1302 real-time clock (RTC) functions similarly to a traditional watch, providing accurate timekeeping using a precise oscillator. It is powered by a small battery (not included) to maintain time even when the main power is off.
This RTC module is perfect for applications that require precise date and time tracking, such as:
- Attendance systems
- Digital cameras
- Automated sprinkler systems
- Time or calendar displays
Its reliability makes it an excellent choice for any time-sensitive project.
Pin Configuration:
- VCC2 → +5 V / 3.3 V
- GND → GND
- CLK → P02
- DAT → P01
- RST → P00
Features:
- Crystal: 32.768 KHz, matching capacitance 6 pF
- DS1302: 8-pin SMD homemade chips
- Tracks: Seconds, Minutes, Hours, Day of Month, Day of Week, and Year
