Grove High Precision RTC

The Grove – High Precision Real-time counter is an extremely precise and low-consumption RTC for Arduino projects. If your application requires high-precision timing providing, please don’t hesitate to get one. According to the name, it is easy to know that the Grove – High Precision RTC is a more accurate real-time clock compared to Grove – RTC with the regular clock chip DS1307. The heart of Grove – High Precision RTC is PHILIPS PCF85063TP, which is a CMOS chip that is optimized for low power consumption, the typical current can be less than 1.2uA in a certain environment. All addresses and data are transferred serially via the two-line bidirectional I2C bus, of which the maximum speed is 400kbit/s. An offset register allows fine-tuning of the clock, and the registered address is incremented automatically after each read or written data byte. Highlighted Features Provides year, month, day, weekday, hours, minutes, and seconds based on a 32.768 kHz quartz crystal Clock operating v
