DSK-00047 Real Time Clock Shield
The Real Time Clock Shield Kit allows you to build a Digispark shield which connects a DS1307 Real Time Clock to the Digispark development board. The DS1307 communicates with the Digispark over the I2C bus. The Real Time Clock Shield can be used to keep accurate time even after the device is powered off. This shield allows the Digispark to be used to make clocks, alarms, or add time and date data to any project.
