PCF8563 PCF8563T 8563 IIC Real Time Clock RTC Module For Arduino

Product Features
The PCF8563 RTC board provides real-time clock / calendar capability that can be battery-backed by the board and can work independently even when the MCU is off.
Low-cost, extremely accurate I2C real-time clock (RTC)
More stable and accurate than the DS1302 or DS1307
Support I2C bus cascade (through the pin, the dock docking mode, you can use more than one I2C module)
Wide voltage range: 1.0-5.5V
