1 item left


If you want to make your own electronic watch, an RTC (Real Time Clock) module is necessary to generate the right time and with very low power consumption. This tiny RTC module is based on the clock chip DS1307 which communicates with microcontrollers with I2C protocol. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap years. This module has really low power consumption, serving you for more than a month with a CR1220 battery.
