An RTC (real-time clock) module is a digital clock, used to keep track of accurate time even whenever it is located within low power mode or a power supply is turned off. These modules have a controller, a fixed quartz crystal resonator & oscillator. RTCs are designed in an IC form that counts seconds, minutes, hours, days, months & even years so these ICs are used in almost every electronic device particularly when the device needs a form of precise timekeeping like personal computers, … [Read more...]

RTC or Real-Time Clock is a timekeeping device that is used in various time-critical devices like GPS, data loggers & servers. Generally, RTC modules are available with a battery setup where it keeps the RTC module running when external power is not available. This module maintains the Data and Time up to date. So RTC module provides a precise time and date when we required it. There are various RTC modules available like DS3221, DS1307 & DS3231 where these modules include an oscillator, … [Read more...]
