ILLUSTRATED ASSEMBLY MANUAL HKA07IP'1
RTC shield
Add a real time clock shield to your projects to ensure
accurate and easy timekeeping. While the shield keeps track
of time and date, the controller can focus on other tasks.
for Arduino
®
Features
• based on Maxim-Dallas DS1307 IC
• counts seconds, minutes, hours, date of month, day of the week, year and leap-year
• 12 or 24h system selectable
• AM/PM indication
• large user community
• requires 1 Arduino UNO™ (not included)
• stackable design: the shield can be stacked with other shields
Specifi cations
• I2C interface
• accuracy: 20ppm (depends on crystal)
• power consumption: 1.5mA
• with backup battery holder (500nA when running on battery)
• dimensions: 68 x 53mm / 2.67 x 2.08"
