The Velleman KA07 RTC (Real Time Clock) Shield Kit for Arduino Uno

Extend the data-logging capabilities of your Arduino UNO® with the Velleman KA07 RTC Shield Kit!  The KA07 shield keeps accurate, real-time date and time reads, allowing the microcontroller to focus energy elsewhere. Customize your time preferences by choosing a 12 or 24-hour schedule and programming between AM and PM.

Downloading the software library (under downloads tab) allows you to manage the LED frequency on the shield. The shield has low power consumption and a backup battery to give power when the shield is not active. The KA07 electronic kit is somewhat advanced and does require soldering.

This is an accessory shield that requires Arduino UNO® (not included).
