RTC Pi
The RTC Pi is a battery-backed real-time clock module for the Raspberry Pi and other compatible single-board computers. It keeps track of the time while the Raspberry Pi is switched off and allows it to retrieve the current date and time from the RTC Pi when it is switched back on.
This knowledge base section contains articles and tutorials on the RTC Pi, showing how to use the expansion board.
