ماژول ساعت فوق دقیق DS3231:
The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. device incorporates a battery input and maintains accurate timekeeping when main power to the device is interrupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line.
It includes a rechargeable battery backup. This module also has a header with a pinout specifically designed so that it can be plugged directly into the IO header of your Raspberry Pi without any need for additional wires or soldering.
Applications:
Servers
Telematics
Utility Power Meters
GPS
