This Real Time Clock (RTC) is the most precise you can get in a small, low power package. The beefy package contains the crystal inside the chip. Right next to the integrated crystal is a temperature sensor. That sensor compensates for the frequency changes by adding or removing clock ticks so that the timekeeping stays on schedule. There is also an EEPROM AT24C32 to supply you 32K EEPROM to store your data, which makes it the best choice for your application that needs time recording. With a coin cell plugged into the back, you can get years of precision timekeeping, even when main power is lost. Great for datalogging and clocks, or anything where you need to really know the time.
Real Time Clock Module - DS1307
This is a real time clock (RTC) based on IC DS1307 that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. ..
Wave DS1302 Real Time Clock
This is a RTC from Waveshare that uses the DS1302. Interfacing the DS1302 with a microprocessor is simplified by using synchronous serial communication. Only three wires a..
