Linker Kit Real time clock

 

The RTC module is base on the clock-chip DS1307 which supports the I2C protocoll. For the exact display is a lithium cell battery (CR1225) required. The clock issues seconds, minutes, hours, days, months and years. The module still has still the right date if a month has less then 31 days. Additionally, the clock considers even intercalary years. The clock works in 24 hours or in 12 hours format with a AM / PM display and it is applicable until 2100. If the module is only supplied with the primary power supply, it will not be working correctly because the cristall is not able to swing.

For operation is a Linker Kit baseboard (for the Arduino, pcDuino or for Raspberry Pi A, B, B+)as well as an Linker Kit connecting cable required.
